Dude I’m traveling to Texas in a few months and I didn’t realize how close Dallas/Fort Worth, Houston, and Austin are. It’s like a triangle, 2.5 to 3.5 hours between either city. Waco and San Antonio sit on the line between Austin and DFW.
These cities are linked by a rather nice highway system from what I remember last time I was in TX, but to the best of my knowledge, there’s no high-speed rail, only rail that’s slower than driving most the time.
Why? Texas should be embarrassed. Especially with Houston being so close to Galveston, which is a pretty damn good port.
