15 is a nice drive. 81 sucks but there are some nice views as you go through Schuylkill County (starting around MP 112). You can jump off 81 at McAdoo (rt 309). Follow 309 south for a short stretch then turn left at the first light. You’ll be on Ben Titus/Quakake Rd. That will take you to Weatherly. Follow signs for White Haven and you’ll be able to pickup RT 940.

Ben Titus/Quakake Rd is really nice. It’s a mainly flat and straight road that runs through a narrow valley.

Adding some more… take the first exit in PA off of 15 and head north on Emmitsburg Rd. That will take you straight through the battlefield and into the town of Gettysburg. Travel through the center of town and follow Business rt 15. You can follow that up to rt 394 where you can jump back on 15

Here’s the route. Godspeed
