I have a few friends that ride out to Bushkill Falls that is in the Pocono region of Pennyslvania every year. They claim that it is a great ride and that once you get to the Falls that it is all worth it. They do say that it is a long ride on the bike since none of the roads there are straight for any length of time.
I was here once. I did not ride the bike because it would have taken forever to get there if we did. We drove the cars and it is an amazing place. We did see a lot of bikers around though so I would imagine that a lot of people from PA take this as a ride for a day.
