Hey mate, i go to Czech every year for two weeks snowboarding, except this year as im off to NZ for five weeks,
but anyway, europe is having a absolutly crap winter at the moment, i.e there is next to no snow as yet, where they would normally have a good 1-2m by now over that way, i would leave it untill at least end of feb possably getting to the end of march, but whatever you decide, trawl the net for the latest on the snow..
Cheers
