Thanks for the info. I think I will stick with my local BBQ company and their wood chunks. They had a pretty good price on a box last time I was there (only had hickory though, waiting on the others.)
I usually try to shy away from the bagged product at the big box stores - usually way over priced compared to what I can get elsewhere.
As a side note - anyone know if sugar maple is useable for smoking? The neighbor has to remove 5 trees from his yard due to septic tank issues and 3 of them are sugar maple (the other 2 are locust, which I have no interest in).
