After living in Colorado for 14 years, my recent move to Arizona has certainly been a change in scenery. One thing in particular got to me. They have these thorny plants called prickly pears. They're mistakenly called cactus by some folks. Anyway, they're green and have flat paddles Some of these plants get quite large.
My father's house, down the road from mine, has a batch of prickly pears that look like little green men from some flying saucer movie. This is especially true at night. I've looked out in the back yard and had a jolt more than once. I think I'm starting to get used to them. I guess the solution is to simply not go over there at night. No one else seems to think they look like little green men.
