Prospect Park & Purgatory Greenspace, right off Prospect Ave. I've rode their once and it was a decent trail over-all...towards the end I found myself having to doubleback as the trail seemed to deadend, but I had a newbie with me so we just jumped on the road back. I probably made a wrong turn someplace.kill phil said:Recently spoke to someone who told me there were "new" trails there. Something along the lines of "Prospect Park?" Anyone with info?
