We are traveling from Mankato, MN to Columbus, OH on July 5th...making the entire trip in one day. We will then be going from Columbus to Washington, DC on July 9 - again in one day. We have 3 children: 12, 10, and 8. We're making a big deal about how many states we'll pass through on our drive. Wondering if anyone has any suggestions for short stops where we could take a break and just take a photo or 2 to represent that state. Already thought of the "Welcome to..." signs at the state border, but would like to be more creative. Don't have to be big tourist attractions or anything, just some things that the kids might enjoy right off the interstate? Any ideas?
