Midland Texas. It's a pretty good sized town, and it really doesn't have many good barbecue places. It's also a REALLY great town if you have a family. I lived there my whole life up until I moved to WY six months ago.
Most folks I know that want good BBQ get it off the pit in the back yard. Opening a BBQ stand/resturant/joint in Texas would be a stupid idea unless you can run in the red for 5 or 6 years trying to get established. And then you would probably end up bankrupt anyway.
If you want to make some money opening a BBQ joint, send me a PM and we'll talk, if you want to live in texas and open a BBQ joint (and hell who wouldnt want to live in texas, greatest place on the earth to live IMO) probably stay away from east texas, there are BBQ joints all over the place already.
From your post I see you are in Florida. I grew up in Florida (Titusville and Delray Beach) and now live in Houston. The BBQ is a little different out here, more brisket, less pulled pork, alot more mesquite instead of hickory, the sauces are a bit different. It may take you a while to get a following. Good luck and I hope to see you in Houston.
