I made two of the three from that post but, you know, there are literally hundreds of grill rub recipes. Allrecipes has more than 50. About barbecue and grilling has a top ten. The BBQ Pit Boys have a recipe. How wrong can you go with something called "Meatheads Memphis Dust"?
Anyway, if you know a guy who loves his grill, I can highly recommend making some rubs.
(It occurs to me that I didn't take pictures of the actual rub, but, you know, it looks like mixed spices in a jar.)
