When I moved to south of Fort Worth in 90, we had a cold spell. I was in the yard when my neighbor popped out. I said: Beryl, I did not know it got this cold here. He replied, boy don’t you know there are only two fence posts here between you and Canada.
Phoenix gets cold from time to time but not the bone chilling cold Texas just went through. I worked in Canada for a few years. You would get freeze warnings. In Phoenix a freeze warning means cover your plants. In Canada it men’s exposed skin can freeze in 10 minutes.
