I’ve slept on the ground without a tent during the southern Arizona tarantula migration (it’s not really a migration, but people call it that). If any crawled on me, it didn’t wake me up.

I was working in the desert near Toiyabe back in '90's. My partner and I were waiting on some heavy equipment to be dropped off at our location. Drinking coffee, smoking cigarettes....

"Look, the desert floor is moving," I told her. "Look, for real, the sand is....moving like it's liquid." I got out of the truck, and there were thousands, thousands, of tarantulas all headed west, northwest. Eerie.

As far as I could see the valley floor, there were tarantulas covering every square foot heeding the call.
