Welcome back to the new NEFF. Take a break from Twitter and Facebook. You don't go to Dicks for your fly fishing gear, you go to your local fly fishing store. Enjoy!
Go over Schooleys Mountain and into Hackettstown - cross over RT 46 and follow signs for the hospital - you'll pass Stevens State Park on the way. The falls will be on your right. Maybe someone can be more specific as to names of roads and distance.
