Well....having lived in Burkburnett, Texas for about ten years (1959 to 1969), and having played in bands that traveled over a large part of Texas, I can say that Texas is like a lot of other parts of the country...BBQ changes depending on what part of Texas you live in... But fortunately..... It's pretty much "all good"...
I am also fortunate to be able to get a taste of Texas BBQ any time I want to drive about 45 miles (one way...and I do this about twice in three months usually), as there is a place in Castroville, CA. that is called Central Texan BBQ, and is owned by a "gentleman" by the name of Don Elkins, who is from Plano, Texas. This place is pretty cool, it has a "funky" old Texas "dive bar" decor, with sawdust on the floor, picnic tables in the middle of the rooms and home-made plywood booths around the walls.. He serves, beef ribs, pork ribs, beef brisket, turkey, chicken, sausages, ham, and I believe, pulled pork....and everything I have ever gotten there was great, with the possible exception of the chicken, which I thought was a bit dry, but it was still good!!!
