An amazing experience to take Spencer down to Long Beach to participate is a summer water camp for people with disabilities.

There were Jetskis that trailed the boat as spotters and folks in the water to keep him pointed the right way until he said "HIT IT!" and was up and skiing! 

The rigs are great and have a "saddle" he could sit in. There is a large center ski and two small outrigger skis for stability.

They taught him all the hand signals to give to the boat but told me that he only used two: "Go faster" and "Do it again"
