I would like to mention a few local favorites and what I feel are some of the best rubs I've had so far. the first one is well known in the Memphis area because it is made by none other than Frank Vernon ( owner of The Bar-B-Q Shop)
it is called "Dancing Pigs" and can be ordered from their website www.Dancingpigs.com
The other is "Woody's BBQ rub" made in Waldenburgh , Arkansas and is well worth trying .
And of course I saved the best for last , you cant go wrong with any of the spices and rubs made by Papa Shaka (a forum member).
Oh well, just thought I'd throw those into the mix.....enjoy
