Smokin' Als St. Louis
Well, St. Louis is a bad BBQ city. So, being number 1 in a place with pretty crappy BBQ doesn't really say much. I went there once and wasn't thrilled. It's kinda-sorta TX style and I prefer TN style.
Secondly, RFT voters tend to vote for the first place they think of. Do people really think Hardee's has the best hamburgers, McDonald's the best fries, and Pizza Hut the best pizza? They've all won at some point in the last 20 years. Also, they don't always vote based upon personal experience but on what they've heard.
