daystalker,
We're meeting at the Des Plaines Conservation Area in Wilmington. It's right off of I-55.

I know some people are coming from Hangover Park... er, I mean Hanover Park. I'm headed there from Carpentersville. It's about 75miles from my house, but it's an easy drive thanks to light traffic in the morning and the tollways.

I take I-90 to 290/355 (head south). I-355 to I-55. I'll get the actual address so you can mapquest it.
