Wow, I'm impressed by your knowledge of different kinds of cacti, including the scientific name. Yes, they are pretty nasty. I want to tell you something you may not believe. This guy is no more than a foot high. I got on the ground to take this shot.
Thanks for the visit, Adam,
Hey Michael, very funny, so they jump on you as you pass by? You know something, I think you are right, the little devils do jump on you. Well, after my little run-in with this guy's bigger cousin, I tread very carefully.
"As an adolescent I aspired to lasting fame, I craved factual certainty, and I thirsted for a meaningful vision of human life - so I became a scientist. This is like becoming an archbishop so you can meet girls."
