RE: Texas BBQ in I20?
Bluemaxx, there's a place I used to stop at quite a bit; Blalock's in Mt. Pleasant. As you're heading west, I believe it's the 2nd Mt. Pleasant exit. Just north of I-20 a couple of blocks.
Haven't been there in years, but I've heard it's still good.
There's an east Texas chain called Bodacious BBQ that is good, so if you see one of those, they're worth a stop. The original is in Longview. I don't know if they have any along I-20.
