You and DePaul son can catch the FLW studio and homes tour in Oak Park, just 9 miles west of the loop. Do it when you visit for fall - the colors should be stunning. You can also do a walk-by/drive-by in River Forest, the next suburb west of Oak Park across Harlem Avenue. Most of the FLWs are west of Thatcher Rd, but the non-FLW homes in River Forest east of Thatcher/north of Lake St are pretty spectacular, too.
