Oh, here's update on the insects from my first pictures near Guadalupe Nat. Park. My friend who's a professional bug-man sent me this in regards to my RR:
"Very sweet. Wish I’d known about it sooner I could have told you that yes, tarantulas “fangs” can penetrate skin and that big red bug is a mite. I don’t recall the species though."
Good thing I left the gloves on, eh?
