I wouldn't say so.
The skaters ('round here, anyway) all seem to pressure each other into dressing the same, doing the same tricks, acting the same, and liking the same music. That's fine, if that's how they want to be - skating's much more fashionable than trials.
Being that trials is so much less fashionable, there's a broader tolerance for what a group will and will not tolerate. ...Or maybe we're (riders) all just a hell of a lot more stubborn than skaters
I don't think it's as different as the guy above implied, but - unless it's just the places you've been to (though I'd doubt that) - I don't think it's a similar scene, either.
