We left San Angelo in 1992, never to return to live there (knock on mesquite, live oak, or pecan wood) - VorGuy's parents and sister's family live there. We visit.
Seriously, folks, in college in the 1970s, 1/4" (yes, that is one quarter of an inch) of snow caused accidents as people spun out of control on icy streets.
There were no snow tires in town - certainly no one around the college was using any, the few snow shovels had been brought by accident when moving from "up north" or were gotten as gag gifts (a joke).
No one knew how to drive on snow - especially not the little 18 year old college freshman who hit our new red Pinto (only time I remember getting a brand new car - it was an accident magnet, I swear) when she spun out of control trying NOT to hit someone slowing to make a turn in front of her - no traction meant no control.
Students were walking in the snow because it was less likely to cause slips & falls than trying to walk on sidewalks frozen as slick as glass...I was one of them!
There were a lot of us from the area who hadn't seen snow in eight years or so. And there was no sand, salt, or snowplows closer than a six or eight hour drive due north in warm weather (meaning you could go fast, not creep along on snow covered roads).
I remember one of the dry creek beds flooding and there was a foot of water washing over the "bridge" at a park as well as under the bridge - they had to install a new bridge later that year, as it washed out....the area is "semi-arid". And windy - so wind chill will freeze any available moisture a lot faster than you might think it would.
