My best trick is a tre flip and i'm only 12 but lots of 12 year olds can porbably tre. My friends and I live in a neighborhood so there is no gaps but a few. We just found out about one and I landed a kickflip off of it still trying to get a double. Here is a link if you want to see some of my videos.(They suck)
