As wet as it is here, I really need to see more of that rain catchment system. As for the produce perhaps you can barter with it for something you don't provide for yourself, or donate it to families in need. I'm considering putting some type of green house/ grower system over the septic tank. It's shallow and snow never covers it. I figure if it's warm enough to melt the snow then if I cover it with black plastic and set some beds on top and cover those with a tent of clear plastic I may be able to grow some greens during the winter time. Any thoughts on this idea? Right now the chickens go there and scratch in the shallow soil and stuff I have dumped on top of it.
