如何亲手制作一个小U池视频教程(How To Build A Mini Ramp With Billy Rohan)

前几天还有滑手在看了Nathan在海南修小U池的照片后问mini ramp该怎么修，昨天Transworld Skateboarding的网站就登出了一个完整的mini ramp修建指南视频，讲的非常详细，我都有冲动来做一个，可是做一个放哪啊，哎。
What’s the best way to upgrade your tranny skills? Get your very own mini ramp. But unless it’s well built, your transition will only last so long. Watch as Billy Rohan leads you through the steps of in indestructible mini. And let the endless ramp sessions begin.（From TWS)
