Wow, all these stories sound very familiar.
When I was about 10 my dad bought a "fix 'er upper" outboard since he suddenly decided that we would be water skiers. To this day, I'm not sure what possessed him. We then free skied for the next 25 years and went through two more boats. All this time I knew you could do this sport on some sort of "course", but had never seen one.
Then, with small kids and still not finished school we nearly gave up skiing. And even, (tough to admit), looked into selling our I/O and getting a sailboat.
Then, on a lark, my dad and I drove down the highway to McClintocks and had a lesson. This was 4 years ago. The first time through the course I had no ideas which buoys where for me and which were for the boat--I was so confused. By the end of the lesson, I had run 5 at 28mph. I was hooked and wondered why no one had told me about this say...20 years ago. Within two months we had ordered a Moomba Outback and that winter I ordered an EZ-Slalom course. I have now run 32' off once and am trying to master 28' off (34mph).
My wife (who is loving her new Lyric ski and bindings, BTW) complains that I have nice winter hands and horrible rough summer hands.
