When did the speed limit change for thinly populated counties? I remember seeing an article about proposed legislation, but I haven't been more than 50 miles west of I-35 since 2001 so I've never seen a higher speed limit than 70 in Texas.
It was nice to run around 78 or so and every now and then be passed by a DPS cruiser. The best though was some idiot in a little blue sports car with one of those ugly bolt on spoilers blow past me probably doing 120mph or higher. Later we saw him pulled over by the DPS. About 30 minutes later, he blew past us again going close to Mach 2.
