Remember the gas shortage in 1972? This caused speed limits on federal highways to be dropped to 55 mph. As it turns out, Texas put up the new signs 6” too low. The state had to go back and raise all of the signs because the Feds said they would lose their federal funding if they didn’t. This caused one Texan to say:
Look at the bright side. If the Feds had done it, they would have lowered the highway 6”.
Sadly, I think they’re right.
I remember seeing the gas lines on tv but there was never a shortage in our area of Texas.
