David,
Your customer service and products are already legendary. I largely lurk on these forums these days while still driving my BDR like a angry rabbit.
I came across this today and couldn't help post it as there seems to be some progressive ideas on wheel chairs.
Good on you for being a champion of humanity and a beacon of reason for the rest of us to try and emulate.

Hope it helps or adds in any way possible.
All the best,
Sean
