There are at least three 2m sailplanes in NE Ohio that are flying. I have three of them that I fly out of my backyard. These are thermal gliders, not slope soarers; a 2m riser, an old 2m spectra converted to lipo and a Tower Hobbies Vista. I am not aware of any clubs specific to sailplanes but most rc clubs have at least one guy who flies them.
PSB - Why haven't you built your sailplane? You don't need other people to enjoy them.
