I buy mine at Berry Brothers. When you drive in, to the left hand side they have a section where they have chunks of wood that is bagged in heavy duty plastic bags. this is how I buy my smoking wood. I found that adding a whole piece of firewood was too much at one time and it would raise the temperature too high. I started cutting my wood down with a chop saw but when I saw they sell the same wood in chunks, bagged, in addition to logs, I tried the chunks and it works great for me. They usually have at least 5 to 7 different kinds of wood. I use a mixture of pecan and oak,. the oak last longer in the fire.
