Yep, I'm here in the biggest city in the world. HUGE! It's my second time here and I'm still in awe. Wow! We ate the yummiest tacos al pastor tonight. Really, really tasty. I have been off of meat and caffeine since November, but decided I would have both while on this trip. I'm not sure if either of those things agree with me at this moment. We shall see. Viva Mexico!
