I am looking for ideas to take my family of three (11-year old son) on a road trip from Chicago over March 25-April 2 spring break. Preferences are:
1. One way mileage less than 700 miles.
2. Destination somewhat warmer than Chicago.
3. Things to keep 5th grader entertained.
4. Proximity to nature preserve, park, etc.
All suggestions are wlecome. Thanks in advance.
