stole 3 plastic barrels from some random car detailing shop, built a frame with 2x4s and used a 1 by 6 on the top and curved it by staggering the heigh of the 2x4s we attached it to. then we attached the pvc by screwing up thru the bottom. we built two 10 foot sections and spliced them together. as you can see, by the end of the summer it broke apart and then we just started ollieing it for fun. It also worked well as a rail in the winter.
