I want to build this baby: http://www.carryfreedom.com/bamboo.html#2 . An acquaintance gave me a new (less than 500 miles on them) set of aluminum wheels for my commuter, so I can use the old steel ones for the trailer. All I need now is a local source of straight, strong bamboo poles. Do any of y'all have any ideas where I might look for good bamboo in Colorado? I've seen some at a nearby garden shop but it was not very good quality; more for decoration than construction.
