I've only met a couple people that have a similar riding style to me, so usually even if I'm at the hill with a group, I go off on my own. Sometimes I'll meet up with them for some "fun times" laps but then I'm off again in search of secret powder stashes while they go on scenic cruises.
Boarded with a guy from work the other day that blew me away. He grew up in Calgary though so has been riding rocky mountains and parks since he was young. This guy pushed the freestyle aspect of my riding heavily. We'd find a little kicker or drop and he'd just go for it, so I followed and had a blast. Normally I'd scope things out a little more before hitting something. I spent much more time in the air because I was riding with this guy!
