I always thought that the Rumney crowd was pretty savy but there seem to be exceptions.
There are many good climbers there, but there are quite a few who would be a danger to themselves in a gym let alone being responsible for themselves outside. I was there a few weeks ago. Three guys were climbing next to use who met up in the parking lot. The guy who was going to lead ask one of the others to belay and he said that he had not lead belayed before. The third guy said that he knew what to do and belayed the leader up, it looked pretty sketchy. When the leader reached the top he clipped in some draws and told the belayer to lower him down. Apparently this meant take your hand off of the rope and let er rip. If it were not for alot of friction between the rope and the coarse slabby rock, the leader would have sustained much more than a sprained ankle when he crashed to the ground with a resounding thud. I remeber a leader there a few years back who fell after clipping the third bolt on a climb, flipped becasue a foot was behind the rope and came to a rest inches from the ground. This person was shaken, but not hurt. He then remarked how lucky he was to have such a good belay, yikes! Scenes like this are not uncommon at Rumney. Ten years ago this was not the case, but more recently, just like at the Gunks, dangerous people seem to be lurking around just about every corner.
