How many people here have surfed? If you haven't, then maybe you need to try. Before you say it, I live on a small private lake with a SN200. I love to ski, but...I love when my neighbor's are surfing and I have time to join them. It's super fun and if you are trying to improve, not necessarily easy. (try a 360) Also, try surfing in the ocean, that's a serious workout! Personally, I found it fun to "practice" surfing behind a boat to improve my ocean surfing. I'm not sure why we have a natural tendency to bash others that are different but it's slightly disturbing.
Bottom line... skiing is alive and well, but it's always been a niche sport. Enjoy a truly awesome sport but embrace the fact that other people are outside enjoying being on the water as well.
