I am driving across country from Philadelphia to San Diego. Will be on I-40 for quite a while... and the states I will be going through in that area will be Tennessee, Arkansas, Oklahoma, Texas, New Mexico, and Arizona. I suspect that there are a LOT of great BBQ spots close to the interstate in the TN/AR area... probably many that I wouldnt find just by driving through there. If anyone can give suggestions where to go for great BBQ or other regional specialties, I would love to hear it! I am open-minded and up to trying just about anything! Thanks!
