ok got 80 or so feet of treated 2 x 6 the poles are sunk in dirt so 20 years tops before they start to rot through. the 2 x 6 should outlast the poles but because they are 12 foot spans i will either have to double up 2 x 6 's to make 4 x 6 or use diagonal braces.
anyone know how heavy a grape vine gets by foot?
