Not sure about ephrata... but you can come to ours! 100 bikes on average. 1st sunday of every month. Route 125... right off 81. Right outside of hegins... towards ravine. The 3 mile straightaway by the overpass. Hit the twisties (they're awesome) then come to the straights and be a squid! It's a good time. If you got info on the ephrata one though let me know!! I'm game!
