I was recently at the Buffalo Garden Walk where center city residents open their gardens to the public for a weekend (wonderful event by the way). One of the gardens had what I would call a rain arbor. They built an arbor with pvc pipe across the top, holes drilled in the pvc pipe and created a "wall of rain" that collected in a trough at the bottom and recirculated. I wish now I would have questioned the homeowner for some direction. After I got home (70 miles away), I thought, why couldn't I do something like that. I'm going to experiment, but wondered if anyone has seen any directions for something like this. Thanks!
