Dennis,
Do you have any wood workers that use a lathe to make bowls, dishes or furniture near your home? I have two such people in close proximity and have just about any kind of wood I want. I cross cut the pieces 1 to 1 1/2 inches thick and then band saw them into 1 and 2 oz pieces. I stay away from exotic woods that could be poisonous or moldy. I stick to mild fruit trees (like peach, apple, cherry and orange), Red Bay, sugar maple, alder, pecan and hickory. I don't use oak, maybe up North its OK, but not here in Florida. I order my hickory from Cookshack.
In addition, when my friends travel I have them pick me up a log (fire size) of whatever I can't get here. My neighbor brought me back six logs of alder from his Alaska trip this summer. One friend brought me back a sugar maple log from Maine and a son picked up some frozen orange tree limbs from his back yard. It's fun to collect them, but I'll never smoke them all using 3-4 oz of wood per cook.
