Funny story. Yesterday, my Chef told me had spent his day off trimming his Pecan tree. I immediately perked up, and asked him what did he do with the wood? He laughed, and said the big stuff was going into his fireplace, and the smaller stuff went to his neighbor for smoking.

Locally, I've only been able to find applewood chunks and chips at Barbecues Galore. If you just need chips, you should be able to find them at Central Market, Academy Sports, and even sometimes Kroger. Of course, there are tons of places to buy them online. Hope this helps.
