Thanks, Jeff Burrows Hi Jeff, I don't know where you live, so I can't be too specific about sources for wood. You will find that I only advocate cooking over the coals of woods, not while the wood is burning. You ought to be able to pick up a quarter cord reasonably. Cabinet shops, pallet manufacturers and other manufacturers using hardwood have lots of scraps. They'd be happy for you to haul them off.
Tree trimming services have lots of limbs to dispose of.
When you travel, keep an eye peeled for wood. I ran across about 200 cords of pecan that had just been trimmed and was free for the asking. Remember, unless you intend to reduce the wood to coals, a little goes a long way. Charlie is thinking of adding wood to the Barbecue Store. Problem is freight.
