rediculous thread i know, but there are two sides. europe has had really good snow on average this year, but places like alta still gets it better. however, no resort in north america could come anywhere near matching the terrain of top euro resorts like tignes, verbier, chamonix, lgrave, engelberg. furthermore, even the euro parks are getting there with places like laax and les deux alpes really stepping it up.
as for the idiot who said why isnt the x games held in europe... i wont even dignify that with an explanation. EXPN? and the olympics?? what a fool.
in conclusion, north america- better/more snow, europe- better terrain. parks, mammoth etcstill have it, but only just.
