Great
Allegheny
Passage
the GAP is an incredible ride - incredible experience
especially the sections near Ohiopyle PA and then through Meyersdale toward Frostburg Maryland
not exactly close to you - but still not too far and especially when you consider bikers from all over the US and world travel to ride the GAP
much of the GAP is remote and tree covered and tends to be cooler than surrounding areas - so it can be a decent if not ideal ride even during hotter times of the summer

Some really nice photos there! I did the GAP/C&O last May.
