Exactly as @vtmecheng said. Most people have access to these so called sports and can relate. How many have access to slalom skiing let alone a course. I live 2 miles from the river and each year I get closer to throwing in the towel on this sport I love. With all the traffic, constant maintenance from boats running course over or using it as an obstacle course its starting to get more aggravation then fun. If I had a private site I could join with in driving distance I would just sell my boat and join. I know of one but they dont want any new members. I find around here at least most people like to keep there spot`s with a course a secret.
