You dont really have to know anything to make it fun.
Hopping backwards on your tire is fun, small tire pivots and spins are fun to. I prefer just bouldering though. Finding a pile of rocks about 30 feet high and hopping my ass up it.
It's awsome to, because we have a few open pit mines where I live, and there are piles of boulders that are monsterous. the tallest is around 60 feet or so, it's a hell of a work out to get to the top but it's so gratifying when you do. It can take around 40 minutes or so, then going down is the hardest.
