Crossing the line separating Indiana and Illinois sometimes means dealing with different laws and customs. Readers are asked to share ideas for this weekly feature. This week: Pumpkins.

The crisp nighttime temperatures this weekend hint at autumn and retailers are getting ready for the season by preparing to sell all things pumpkin.

Odds are if your favorite coffee or cake or candle contains actual pumpkin, instead of a chemically-similar flavoring, the pumpkin came from Illinois.

Illinois leads the nation in pumpkin production, planting 20,100 acres of the 51,300 U.S. pumpkin acres in 2014. That's nearly 40 percent.

Nearby Will County is among the top 10 pumpkin-producing counties in Illinois. The state also is home to the Libby's pumpkin processing factory in Morton that manufactures 80 percent of the nation's canned pumpkin.

Pumpkin is more of a specialty crop in Indiana with production concentrated in the northern and southern part of the state.

Federal farming statistics show Indiana does not even crack the top five states for pumpkin production.
