Wow. I thought it was hot in Vegas. No, it is hot in Vegas, but it feels hotter here. First day of guide training done. Half the day learning about the park, the second half consisting of a scorching afternoon rock art tour. The heat smothers. It's great to see Hueco in the spring; the vegetation is in bloom, and the meadows are a vibrant green, but it's hard to enjoy. Two more days.
