It's not the mainstream sport that every joe blow on the street with half a brain and zero ambition does. Finding a popular activity that requires skill these days is like a needle in the haystack. It makes me sick to know so many people in their 20's/30's that have given up on learning anything new. I either own extra equipment for friends or used to own extra equipment for friends in a variety of different things and no one wants to do anything because it's either too hard or too dangerous. Mountain biking, waterskiing, wakeboarding, stand up jetskiing, rock climbing, etc etc. If they can't learn everything they need to know in 30 seconds, forget it. I've asked tons of friends from work if they want to do the activities listed above and the answer I get almost every time is "I don't know about that but if you're going to go tubing, let me know".
So basically, if you can find someone who likes to do a lot of these activities, then you've found someone who is a lot like you and the potential for making a cool friend is much greater.
