CL for free is always an option. People use them for planters, line tracks for gocarts dirt bikes etc. Walls for earth ship homes etc. An associate of mine and myself are trying to find funding for a large enough building to install a tire shredder(which we alrighty have access to). As it stands now they go to central Cali to get shredded then to Oregon where a company makes stuff out of the shreds. Everything is in place except the building......
