Here's the background - Have taken the kids camping since they have been 3 or 4. Currently they are 11, 9 and 5 (boy, girl, boy). They enjoy tent camping, hiking and exploring but also enjoy a good water or amusement park here and there. I am a school teacher and have been toying with the idea of getting a pop-up camper or RV for summer use (while the kids still are young enough to like me). So, I thought I could rent an RV this summer and give it a trial run.
I wanted to start small and not go overboard, so I thought 5-6 days would be PLENTY of a test. All the kids travel well and get along. I am looking for suggestions for a trip out of Chicago. The time frame will likely be the days following July 4th (yeah, I know...). I think the Black Hills will likely be too far, but could do a two-day chug out there with a cool stop along the way in MN, spend 2 days and come back. Perhaps a loop down to Mammoth Caves - although my oldest seemed to balk at entering an enormous cave.
Just looking for some ideas as this seemed like the place to go for that.
Many thanks in advance.
