For the first time I selected the regional discussions and happened upon this. I have seen these green signs near me and always wondered what they are for? I guess they are route indicators? After doing a little searching I can find a list of these routes but is anyone aware of a site with maps?
I have to say where I have seen these signs near me and once on a vacation in Gaines PA I would not ride them. The route I saw in Gaines you would get run over in a half hour.
