Ya I know. If they let people drop anything they want in the water, you wouldn't be able to jump in without landing on a pvc pipe or a Christmas tree. Lol. I'm just looking for a little help making and setting a few. I have enough pvc in my back yard to make about 36 structures. And I have thousands of cut off pieces that I can get whenever I want. It's the good stuff too. 6 inch pipe with .5inch thick walls. I even thought about trying to sell some of the pipe. Not sure what it worth, but I bet I could get 3 bucks for a piece of it.
