If your kids have an atlas at their disposal during a trip, the following activity could entertain them for quite some time. Simply have the kids turn their atlas to a particular state. Then have them all try to find the funniest city names for that state. Have them share their findings with all of the occupants in the car.
As a starting point, try your home state? We know of funny names in Idaho, North Carolina, Kentucky, Arkansas, New Mexico, Arizona, Washington, and more.
