The Jan. 11 “Mark Trail.” (James Allen/North American Syndicate)

“Mark Trail’s” current storyline is supposedly taking place in southwest Texas, yet the Jan. 11 strip showed s aguaro cactuses. I am from Texas and have been to Big Bend National Park, in the Chihuahuan Desert, many times.

I also lived in Tucson. The s aguaro cactus does not grow in the Chihuahuan Desert. It grows in the Sonoran Desert. 

The cartoonist needs to take some geography lessons.
