Until the post the other day I had never heard of the Jim Michaels scandal. That is crazy, but it made me laugh because a few years ago we accidentally had our ski buoys narrow on us. We ski a portable course but leave it in all year. Over time the floatation in the pvc was losing its buoyancy and slowly the pvc arm out to the skier buoy was sagging in the middle pulling the buoy in. Since it happened so slowly and we all ski on the same course only we didn't recognize what was happening, but man did we all keep getting better and better. What a good summer that was until we dropped a different portable course in and realized that we actually all still sucked at skiing. So if you are like us and use a portable course, don't forget to replace the internal floatation occasionally.
