Well, I've been out of town and then busy hosting a house guest from Europe, but now I can finally set a date. Let's walk at Waterfall Glen in Darien on May 20th, the weather forecast is warm and sunny. The trail is 9.5 miles and goes in a big circle around Argonne Labs. We won't do the full 9.5 miles in case you are panicking! Park in the lot off of Bluff Rd -- Cass deadends into Bluff, turn left onto Bluff and then right into the entrance where the sign says Outdoor Education Center & guard residence. There is a parking lot back there; you'll also have passed a few small gravel lots on Bluff at the sides of the road. This is not the main preserve entrance. We'll walk by Sawmill creek, see the mini-waterfall, see the ravines. Maybe walk 1.5 miles and turn around for a total of 3, or you can walk more if you wish.
