haha, lose the tight pants, great, thanks. nah, but really thanks.
jumping on to handrails isn't actualy that hard, at least if it's a down hill one cos you can jump on to like a little way down and then you actually jump about a foot high, high, mellow rails on the otherhand, i'd just try to jump over stuff a lot so you know how high you can jump before you try them.
working up to your first hand rail is a lot harder than say your second, it's mainly a confidence thing, when i did my first rail it was shit but i was just mainly shocked i actually got on, just start low and short and relatively steep and make sure you know you can do your grind far enough to clear the steps, it also helps if you can jump the set your grinding down cos then if you go fast at it and pussy out(witch most people including me do) you can just jump the set instead.
