we just got back from canada where we found an adaptive ski instructor with all sorts of specialist knowledge and equipment, and fab with kids to boot. dd2 cried when we said goodbye...
ski banff - sunshine village, his name is jamie
he's also trying to set up a not for profit company providing adaptive summer activities in the rockies too - so if you feel like splashing the cash, i would thoroughly recommend getting in touch! (and, no, i'm not his mum lol)
