Looks like fun! Reminds me a little of Para olympic sit ski racers I have the privilege to work with. Always have a big grins on their faces no matter whats going down & you will hear them give out a yahoo or two as they fly off of bumps!
If you get a chance check them out after the main event this year ... .we have been promised the Para Olympics will get far more air time this year. Hope its true as they are really great to watch.
