Some Good Signs in Gray

It's getting drearier, at least on some days, in Central PA.  Dreary grayness can be reflected rather somberly in old train trestles. But old trestles can also hold a good sign, as this one does in Lemoyne, PA:

I'm not sure this was an official act of signage, or a rogue one. If you're a long time reader of this blog, you'd know that even official signage can be of low quality (see my post this past  summer). As for this sign, it's well placed, as this curve in Lemoyne toward the Market Street Bridge and river is a treacherous one for pedestrians and bicyclists alike.
