Over here in Israel, rappelling is very widespread. There are hundreds of hiking trails that end in rappelling from multiple cliffs from as low as 15M to 150M. It's great because if you bring a long a group, they only need to know basic rappelling which can be taught in 5-10mins. IThis is why tourists usually go on one rappelling trip when they come to israel. I was just thinking that there might be something similiar in the NY area in the states as I will be going there for the spring or summer.
