Renovo used to be a thriving railroad town. With the demise of railroads, the town pretty much "went under." It's still there and still populated, but there isn't much there except for the houses and a couple of bars. The fall foilage there is outstanding though, for a Sunday afternoon drive. Picture Rocks, as someone else said, is near Hughesville. You reach it by heading North on PA Route 220, and it's (this is a guess) about 5 miles North of Hughesville. Vicki
