If you’re interested in the biggest party in Mexico, if not the western hemisphere, go to “Aguascalientes”:http://en.wikipedia.org/wiki/Aguascalientes, Aguascalientes (city, state) for the Fair of San Marcos.
Before you go, be sure to rest up because there’s almost too much to do: bullfighting, cock fighting, casino, concerts, and 10+ two-story warehouse-sized bars packed with beer, booze, and babes. Starting in mid-April and lasting three to four weeks, this party is the largest attraction Latin America. In a hard to believe four day feat, all of the bars, restaurants, and numerous stages are assembled in extravagant temporary structures – complete with marble walls, fountains, elaborate signs, and sculptures. An average night, weekend or otherwise, has more than 35,000 partiers that don’t quit until 5-7 am. For more touristy information on how to get there, where to stay, and what more to expect, visit “here”:http://www.mexperience.com/guide/colonial/aguascalientes.htm.
