Subtle Mistake

Goof: US 34 for Pennsylvania 34 in Gettsyburg

On northbound Business US 15 in Gettysburg, Pennsylvania, I found this goof in June 2013. US 34 doesn't go anywhere near Pennsylvania. Its eastern end is in Berwyn, Illinois. The trailblazer should be for Pennsylvania state route 34, which splits off from Business US 15 north of the downtown area, where this photo was taken.
