www.raiders.ch is the newschoolers community, more or less, for switzerland.
From Lucerne you got Engelberg, Melchsee-Frutt and Meiringen-Hasliberg as the local mountains. Engelberg's got the sick big mountain terrain, and Meiringen-Hasliberg has decent park most of the time. A lot of people hang out in Melchsee-Frutt because it's so small and a tight community. Mostly snowboarders though.
It's switzerland, so just go up to the park and talk to people..
