9 Things That Confuse Everyone Who Moves to Iowa

Move to Iowa, and even a trip to the grocery store can raise questions.

Where does that extra nickel on the receipt come from?

These are the things that confuse everyone who moves to Iowa.

Note: This is general information, not legal or tax advice. Iowa laws, rates, and local rules are subject to change.

1. Nickel Deposit

Iowa’s nickel deposit applies to every can of pop and bottle of beer sold in the state, and it has since 1979.

A shopper checking out at Hy-Vee or Fareway pays five cents extra per container without asking for it.

Nobody explains it.

A newcomer from a state without a bottle law stares at the receipt, certain something rang up wrong.

That nickel comes back the moment the empties go through a redemption machine or across a store counter.

Still water and juice bottles skip the deposit, which throws the math off all over again on the next trip.

2. Reading the Road Grid

Off Iowa’s paved highways, street names mostly disappear, replaced by a straight numbering system built under the state’s E911 rules.

Counties commonly letter the north-south roads as avenues, starting at the county’s western line and climbing the alphabet mile by mile.

Dickinson County numbers its avenues instead, so the pattern isn’t universal statewide.

They number the east-west roads as streets instead, counting up from the county’s northern line.

No street names apply.

A moving truck’s navigation app spits out an address like Avenue K, and the driver has no idea which direction that even points until someone explains the code.

3. Gravel by Default

Gravel makes up more than half of every road mile Iowa maintains, not just a few forgotten farm lanes.

Iowa’s transportation department puts the gravel share at about 58 percent, more than the roads that are paved.

Counties grade and resurface those miles on their own budgets, separate from the state’s paved-highway funding.

A hard rain can turn a smooth gravel stretch into a rutted mess within a few hours.

It happens fast.

A newcomer who parks on the shoulder right after a storm can find the tires sunk past the hubcaps before they’ve even opened the door.

4. Clear-Sky Siren Test

Iowa’s annual siren test follows a schedule set months in advance, down to the exact date.

Every spring, during Severe Weather Awareness Week, sirens sound at 10 a.m. across the whole state at once.

The date always lands on a Wednesday.

Iowa’s Department of Homeland Security and Emergency Management sets it, and county officials from Dubuque to Council Bluffs flip the same switch at the same minute.

Longtime residents barely glance up.

A newcomer who missed the announcement grabs the family and heads for the basement, then learns later that officials planned it weeks ahead.

5. Liquor’s Separate Aisle

Hard liquor in Iowa comes off a different shelf than beer, and state law is why.

Iowa has run its wholesale liquor system as a state-controlled monopoly since 1934, so every bottle of whiskey or vodka on a shelf passed through a state-run division first.

Beer and wine skip it.

They sell through an ordinary, open market, which is why a gas station carries six-packs but never a fifth of anything stronger.

A newcomer hunting for tequila at a convenience store learns the split the hard way, usually staring at an empty spot where the liquor aisle should be.

6. Tax on Candy and Pop

Iowa’s sales tax reaches candy and pop even when the rest of the cart rings up tax-free.

Most groceries carry no sales tax under Iowa’s food tax rules.

The Iowa Department of Revenue carves out candy, soft drinks, and a short list of other items for the full tax rate.

A receipt from Hy-Vee or a Kum & Go can show a taxed line sitting right next to a dozen untaxed ones.

That’s not a scanning error.

A new resident who grew up somewhere with one flat grocery tax, or none at all, double-checks the receipt before believing it.

7. Ninety-Nine County Fairs

Ninety-nine counties make up Iowa, and each one hosts a fair every summer, not just the handful a newcomer might expect.

Kids raise and show livestock through 4-H and Future Farmers of America (FFA) programs all summer, weeks before the Iowa State Fair even opens in Des Moines.

Clay County’s fair in Spencer bills itself as the world’s greatest county fair.

A transplant used to one regional fair a year watches an entire small town clear out for a week straight and assumes something unusual is happening.

It happens every summer.

8. River-Drawn Borders

Newcomers tracing Iowa’s outline on a map notice it first.

The eastern edge follows the Mississippi River, and the western edge follows the Missouri and Big Sioux Rivers instead of a ruled line.

Government surveyors drew only the northern and southern borders straight, using ordinary survey lines.

A transplant used to state lines that run straight for hundreds of miles has to cross an actual bridge to leave Iowa on either side.

That’s just geography.

Dubuque sits on one river bank, and Council Bluffs and Sioux City sit near the other.

None of those cities lines up on a straight edge because the water drew the line instead of a surveyor’s ruler.

9. Hills Nobody Expects

A ridge of hills in western Iowa doesn't fit the flat-cropland picture many newcomers arrive with.

The Loess Hills run about 200 miles along the Missouri River.

They're built from wind-blown silt that piles up to 200 feet deep in spots, layered there over thousands of years.

Only one other place on Earth has loess that deep, near the Yellow River in China.

A driver expecting flat cropland the whole way across I-29 near Sioux City hits a stretch of steep, narrow ridgelines and checks the map twice.

It's the right road.
