Found a site that specializes in Memphis Style BBQ Rubs. Angel's Memphis Style BBQ Rubs has some great recipes and be sure to read "The Story" You can find a link to Angel's as well as other BBQ Rub sites at our, you guessed it, the BBQ Rubs and Seasonings page.
Another rub site added this morning is Knox's All Natural Barbecue Dry Rubs. Check out their blog as well.....some good receipes including a few non-bbq receipes.
