I have a couple apple orchards close buy that always give me a few logs when I need them. I have not needed any apple in over 4 years! I am down to my last log though and it's pretty dry. I also have a guy that will give me logs of cherry from the trees he cuts. Hickory, or Pecan, I usually buy at Home Depot. Oak is pretty plentiful around here also so I usually just cut my own.
