mexico city is absolutely mental! busy busy but really very friendly,lots of people are willing to help if they can.went to a market and it just never ended,we stopped for tacos at a little street vendor and sat on a busy roadside on plastic stools eating watching the mexicans go about their buisness.the main square is Centro Historico with the palace and gov. buildings and about 47churches! they are really big on religion here, catholics. went to see the second most visited catholic site in the world after the vatican where the Guadulupe,its where the original robe is with the picture of the Virgin Mary on it,its in a modern church with mega security was really impressive,they had 9million visitors in december alone last year! with an old church right next to it thats actually sinking into the ground on 1 side its crazy like the leaning tower of pisa. its all set in very picturesque grounds with waterfalls and statues etc. nice time there.
