I want to take a road trip for about 7 days. We will start from Westchester NY. Ideally we would like to go to mid-west but not sure if that is too ambitious as we have to be back on the seventh or latest by the eighth day. We have already been to most of the bigger cities like Chicago, Madison, Denver, Columbus etc. So we want to make this trip more about national park / monuments, smaller interesting cities/ towns etc. Any suggestions about how far should we aim from east coast and any points of interest in Mid-Western states are welcome.
Thanks a lot.
