Dave- Too bad about that wood. Can you get slab wood from a local mill for free maybe to hedge your bets? I think I can here and I think Im going to do that. I cant wait to see how you do when you put vac on those trees of yours. With as good as they did last year on gravity youll have all the sap you want then I bet. I told a local guy what I was doing this year with my 3 by 10 yesterday and he was a little concerned for me. Hes not running a whole lot more than me and he has all kinds of equipment. I like your attitude about it. Too much sap is a good problem just buy more tanks. Theron
