John said there was a Vortex up here. This is a Helo Pad. I imagine it creates quite a Vortex.... Apparently, twice a year, the Helo transports a very large Propane Tank up here, once in the Spring, with a full one, and then picks it back up in the Fall. Bruce stated that with the Winds up there, it is quite nervewracking watching that huge Tank swinging around.....
