Don't know about the wood supply, but as far as where to get "good local NC Pork Butts" - that depends on what you consider "local". I usually get shoulders from "Bethesda Provision Company" in Durham (1712 Stage Road, Durham - (919) 596-2490) . I just bought 20 shoulders at $1.05 per pound; each shoulder weighed between 16-18 pounds. I have previously bought from Nahunta at the Raleigh Farmers Market (919) 832-1848 (Nahunta also has a location near Goldsboro - 200 Bertie Pierce Road, Pikeville (919) 242-4735), as well as from "Tom Inscoe Wholesale Meat", 4130 South Alston Avenue, Durham, (919) 544-1250.
Don't know if you mind the drive to Durham, but I highly recommend "Bethesda Provisions"!
Good luck!
