1 pointI tried Rattlesnake Hill (aka Lime Kiln) in Bolton, MA for the first time last week. I didn't have high expectations but was pleasantly surprised. Some very cool rock spines all over the hill, a trail around an old quarry with some scary exposure and the Ridge Loop trail was really the highlight. Lots of rocky features to ride over and lots of fun turns. Not a lot of vertical but I'll definitely add it to my regular ride rotation.
