Are PA bike routes labeled with signs? Are the roads wide? I know most PA roads are only wide enough for two cars to pass without riding on the shoulder...and there is no shoulder... I have ridden in a car plenty in PA, but never ridden a bicycle anywhere there.
NY bike routes have small signs showing cyclists where the route is. The routes are on wide-shouldered roads, too.

I'm asking because on Google....the bike routes don't show up in PA. Only the bike-only paths seem to show.
What is the advantage to riding on the bike route? Are there disadvantages?

BTW, those pics are beautiful!
