We’re already noticing the changes in species. It is most obvious with the trees and greenery. Everything is mostly scrubs, cactus, and very low growing trees, then all of a sudden we start seeing these huge evergreens and even some grass. It’s pretty cool. I don’t know about biogeographers, my response is usually…”whoa, cool” :)

Debbie, cool! We’ll have to see if we can do Karchner Caverns this time around. If not, we’ll add it to our map of things to do so we don’t forget it next time we’re in the area, it sounds like a spectacular place to visit. We were hoping we might hit Tombstone too but with so many things to do in Tucson, I don’t think we’ll have to time to get to it all this time around. Course that just means we’ll have to come back and visit again.

John, we really liked the Biosphere too. It’s pretty mind-boggling what they created plus all the engineering feats required to make the building air-tight. We definitely want to hit the Kitt Peak Observatory when we’re back in Tucson, especially since McDonald Observatory was a bust due to snow and clouds. I hadn’t heard of rattlesnake aversion training, I will definitely have to look into that. Thanks for the tip!
