The whole time we were climbing the staggeringly rugid path up to the pyramid at Tepoztlan, Mr. "Chatty-Super-Climber" Zam went on and on about how "awesome" it was and how he just "loves a good challenge!" On our way down the mountain, he kept saying how much he prefered climbing up to climbing down. Unfortunately, I can't say the same for those of us who've been living off tortillas and other yummy Mexican food for the past month and are feeling it around the belly region!
