Don't know if anyone is interested...But, here is a 294 mile loop, leaving out of Shamokin Dam, which is 24 miles from Bloomsburg. (We're staying at a hotel there because it was the closest we could find! ;-(
I had to attach the file in .gpx format because .gdb attachment is not an allowed format. Created in Mapsource 6.16.3 using Mapset 2011.4, just open and save in .gdb format.
Route goes through two state forests... I plan on creating another loop that will take in PA 125: Pennsylvania's' "Dragon"... A GREAT twisty road. Will post if interest shown.

EDIT: With Rockbottoms feedback the route has been "upgraded"... scroll down and see "shamokinTour290v2.gpx. (Use that)
