I'm south of you on the PA/MD border and the leaves are peaking here. Sounds like you have a nice ride planned. Look forward to a post-ride report (with a picture or two???)
My buddy and I are riding down to the Copperstate Fly-in at the Casa Grande, AZ airport. It's supposed to get up to 90 degrees by the afternoon. Should be about 110 miles of riding, but nothing to look at in the way of leaves.
