The only two things I would be interested in are Dealy Plaza in Dallas and the Alamo in San Antone. I would then get the flock out of either city...and I'm a native Texan, if that gives my opinion any weight in your estimation.
Yep. Dealy Plaza and The Book Depository.
I’d pass on the rest of Dallas.
The Stockyards are pretty cool just down the road in Ft Worth. Some great museums there too.
