Well as you can tell from my username, I'm not against riding alone.
When I started out as a teenager, one of the main reasons I rode was to hang out and meet new people as I was a bit shy. And I still like riding with my friends... but I've gotten to the point that I don't have to always ride with people.
In addition to the people at my winter house. There are a bunch of people I see riding the park every weekend and we all kind of know each other and might trade a few words on the lift or at the top of the park... but I don't need other people to enjoy snowboarding.
