Hey, switch riding is probably one of the most important riding skills.. It leads into tricks and gets you out of "tight spots" when you really have no option other than to ride switch or bail out.
I read a few posts in this thread with some crazy details on how to ride switch and I also seen people post "its just like riding regular, but backwards". I agree with the guys saying that it is just riding backwards tbh.. it is more or less learning to ride all over again but with your unnatural foot forward. Apply all that you have learned riding with your natural foot forward... to your switch riding.
I posted a video on youtube a year or so ago of me riding with a gopro at Lake Louise on opening weekend. There was only a couple greens and blues open.. so it was a great opportunity to fool around and do some switch riding. Not really a good vid clip to learn from.. but if you do a youtube search for switch riding you will find some instructional videos that might help you.
