I have IBCs that have been cut in half, 55 gallon drums with their tops cut out, tons of plumbing PVC pipe, even an old spa but i doubt anyone would want that. They are filled with lava rock you would need to remove it (can be dumped right onto ground).
I am moving and not taking the large system I have. Instead I am gonna stick with the smaller system I built, I am the same person who hosted a tour a few years ago in cordelia. you can text me for directions to my house (707) 319-9171
Joe, That's a very generous offer. I'm now involved with a non-profit educational AP project with poor teens in Sacramento. This would be a great addition to our 1000-sq.ft. greenhouse, which was also donated and which the teens helped erect. If you see fit to choose us, we would certainly put it to good use.
In any event, best wishes with the move, and glad you are not getting out of AP entirely. I remember you and your system and often tell people about you raising trout from fingerlings to eating size over the course of a winter.
