I voted May, but by that I mean closer to the END of May. Up here in northern IL, it could still be quite unpleasant at the beginning of May. I'm doing my annual ride with my brother (who is from Washington D.D. and currently has a brand new CanAm Spyder) sometime next spring, and the plan is to go to Asheville, so I could be in for a couple days, depending on the actual dates.
