Canadian web site, Push, just rolled out their Virtual Earth integration to help skaters and snowboarders (ok, skiers too) find their local skate parks ski resorts (coming soon), respectively. Users can search and view extreme sports locations on a Microsoft Virtual Earth map, aerial photo and in some spots Bird's Eye Photos. The Bird's Eye photos make for some nice visualizations if you want to really check out the different sites. Additionally, you can submit information for letting them know where there's a specific skate park or ski resort by completing the form and sending it into them.
Yes, I used to skateboard; and, yes I'm now retired as I would kill myself trying just a simple ollie. L.
