Riding quarter/half pipes?
 

Is it hard to ride a half pipe and do the 180 to turn around and land straight and continue going back? What about spines, is it hard to transfer over a spine? How long did it take you to learn that/how many falls?

half pipe....hmm.. that just takes getting used to. i was sorta nervous at first but then a few guys just showed me and told me what i was doing wrong and i could do it great within a few hours.....it's like a wheelie it is hard at first but the more you do it the easier it gets....and the funner it gets.... but it;s not all that hard

spines are a bit tougher than quarter pipes. its basically like dropping-in from the air. when you launch, turn a little to the side you drop in on and its basically the same thing.

ya i forgot to talk about that.....

Drop in 1/4 & 1/2 pipes at an angle. Work the 180s below the coping for a long time, then work your way up and over the coping.
