I wanted to mention that smoking friend Tim in Tulsa is offering a fine selection of Backwoods smokers on his site Backwoodsok.com .
I've not tried one of these but hear that they put out some great food.
Tim carries small backyard units, huge whole hog cookers and everything in between!
If you are interested.. shoot Tim an e-mail or give him a call. I'm sure he would be happy to answer any questions about the Backwoods. :)
