WMBNA.org offers a great map to Blue Mountain in Peekskill, NY. Favorites include Upper Sis, Sis, Debacle (beat the living crap out of me), My Favorite Trail and what we think is the best, MYX Monster. Monster is the type of trail where it flows as long as you can handle the rocks, roots, tight twistys, short burst climbs, drops, and occassional screams of horror because your friend is about to endo and do a face plant on jagged rocks right behind you. We’ve tried Monster in both directions and although either direction is fun, its best starting by the 29 marker (which the map clearly points out!).
Special Thanks to Nelson for doing the on-trail bike adjustment so I could continue my riding enjoyment.
