One of my most memorable chess events in 2005 was my visit to Mexico City in July 2005 (http://chesscafe.com/text/polgar37.pdf)
The event was magnificent! The organization was spectacular! The venue was incredible! It was a first class event from the beginning until the end.
Thank you AKRO company, Casa Del Lago, Astrid, Enrique, Alberto, Jose, Myrna, Saggiante family, and everyone else involved!
