Any dude reading this is likely to wince at the thought of Blue Knob. It’s hard to believe but this really is the name of the highest skiable mountain in Pennsylvania. You’ll be pleased to hear, this mountain sits alongside Spruce Knob, Cattle Knob, Round Knob, Pine Knob and Ritchey Knob. And the river that runs along the base? Beaverdam Creek. Double entendre heaven.
