Breathtaking... I want to go back!
It was the first time in my life that, after 6 hours, I had to say "stop" and come back the next day. The first time in my life a museum took me actually two days to visit. The information you get there is HUGE. My head was spinning. It is really one of the best of its kind and a must if you happen to be in Mexico City and can set aside two days to visit it. I wish I had more time and be able to go back, some of the things there deserve at least a couple hours of study by themselves!
