Awesome!
I am SO jealous that you have those opportunities in your backyard.
There are three things in life that I love to do and require travel from where I live: climbing (in the bike riding sense), hill walking (or non-technical mountain climbing, if you will), and open boat whitewater. I haven't done the last one since before I was married and had children. I used to do some very stupid stuff on rivers in my younger days and it is a wonder that I am still alive. Once I was arranging a shuttle at a raft rental place and they offered to do it for free because they didn't think that it could be done in an open boat. I paid them anyway and had an awesome ride. It was really stupid because we were only one boat.
