Sorry, been busy. Bradford? You can't get there from here! Here's one suggestion, it should be close to your 100-150 mile range. I'll post a couple more ideas when I can...
219 South to Johnsonburg
255 South to St. Marys
255 South to Weedville
555 East to Elk Country Visitors Center
http://elkcountryvisitorcenter.com/drupal/
Leave Center, stay on 555 East
555 East to Driftwood
120 North toward Emporium
Stop at The Little Museum?

Leave Museum, stay on 120 North to Emporium
Stay on 120 into Emporium (4th Street (main street))
Stop at Cabin Kitchen, on right, Eat Lunch
Stay on 120, to end of town
Right onto Woodland Avenue, to 46 North
46 North all the way back to Bradford.
