Don't forget to stop at the Polk-A-Dot drive In, in Braidwood, IL. It's right on Rt. 66, after Romeoville, maybe 1/2 hour or so & just before Gardner, IL by about 10 minutes or so. It's a fifties style restaurant with tons of memorabilia. I did their menu boards & a few other signs over the years. Here's a link...

Oh, and I live about 5 or 6 miles from the place. Maybe we could say hi if the schedules work out.
