Sounds like you had a good ride, we are planning on going up to MD then back down to Va and ride some of the roads I grew up on some are actually paved now. Hope to see you in June at MD.
I think someone sold you a line with the 170. I have only rode on the sidewall once and that was a ony because of the way the curve was slopped. I can't imagine what it would have done with a 170 on it.
