A while back, I was just leaving the grocery store when this mother and son were walking by the VX. Her son was probably about 10 but moderately Downes (SP?). He was so interested in it that she litterally couldn't peel him away. After about 10 minutes, the kid had been all over my Proton (inside & out) about 8 times, she was finally able to get him to go on into the store (I think she bribed him). She must have thanked me 20 times for making her son's day.
They actually did me a favor though. I used to teach Special Ed swim classes and the opportunity really brought back memories of how rewarding that was.
