So, last month we went over the (PS) Phyre Saw. I don't know about you, but as I drive around, there are a lot of giant Sunflowers! If you happen to pass by one of those local farmer markets that happen to be growing those Mammoth Sunflowers, you might want to stop in and talk to them about your interest in the stalks only (not the seedheads.) The stalks, to the farmers are mostly garbage and waste. To us, they are PRECIOUS (PS) Phyre Saw bases and HearthBoards!!! Ask when they're planning to cut them down and if they don't give them to you for free, offer to give them a down payment that you negotiate that's fair, get a receipt and their contact info (in case they forget and cut them down and get rid of them and don't contact you - get your $ back). The very bottom of the stalks up to about 6 feet up is what you're looking for. Good Luck!
