I snowboard. its fun to ride with skiers. in the park you can get different ideas/inspiration from how they do tricks sometimes. And in deep snow and such they can help pack down a trail ahead of you in flatter areas.
Skiers... Snowboarders... same shit different day. We all are out there to have fun. Not to rip on each other. No one goes out skiing being like, "If those fucking snowboarders are sitting at the top of that drop in, I'm going to bash some heads in." Use that golden rule your parents and grandparents told you, "Treat others as you would want to be treated."
