Replying to New Hampshire Urban

Ok I know there have been dozens of east coast urban threads but Im looking for good rails or spots in southern NH, around Manchester, Nashua, Bedford. I hit a decent rail this weekend and I wanna try some more spots but just dont know where to look. Ive seen UNH, Manchester Memorial and the wave rail along the river in Manchester (no clue where to find it). I dont wanna go anywhere thats super obvious or is flooded with cameras.
Please help :)
