Several surplus garbage ones heading for the dump I'm sure on the side of the road in West Jordan, UT. Sitting on Old Bingham Hwy west of curve but before U111. I'm sure that helps so many but there looks to be enough to make about 6-7 cat tubes. Theese are big heavy duty about 3/4 thick pipes. If it wasn't to much work to move em I'd almost pick em up make tubes up and sell em.
