IMBA just posted some info and photos on Rattling Creek--as well as a few other Epic trails, on the Geo Stories page run by National Geographic. It's part of the group's larger mapping project, and it's cool to see a PA trail represented. Look closely at the pics and you might recognize some of the riders.

If you haven't been there, Rattling Creek is a great (and growing) trail system near Lykens, PA, about an hour and a half west of here, not too far off 78. IMBA just named it an EPIC last year. Definitely worth a road trip.
