I'm interested in riding your Poolesville route and would be able to do any weekend other than the 9th-10th.

I don't see an mtb bike in my stable any time soon. I suppose if someone had one to lend me that fit OK I'd consider a ride...

What is it about biking that make you think always about your next bike? I've always got dreams of race or tri bikes, and if the commuting thing goes well I'd love to trade my hybrid for a flat bar road bike.
