Poison "ivy" got me as well - although I don't think it's Ivy. I've never reacted to the ivy, but one of the other's (oak/sumac) get me really bad. Doctor didn't think it was ivy either, not linear enough. Regardless it sucks, waaah!
The canal is the D&R canal, pretty much where the ride ends and you turn around. The new section was a bit farther on from the water crossing where you turned back.
Sorry, last name was illegible...Michael Rejda.
Thanks J's for organizing and letting me swing an axe in a legal way. Nice to work with everyone and hope to see you on the trails
