I've been to Mexico more than any other country outside of my home country of USA.   One of my most memorable trips was in October 2003 when I went to Mexico City and visited Teotihuacan and Tepyac. Also during this trip I visited Puebla, San Luis Potosi, Leon, San Miguel De Allende, and my favorite...Guanajuato.  I loved Guanajuato because of its location, architecture and I was there for Cervantino Festival and Dia De Los Muertos.

Aside from this trip...I've also been to Cabo San Lucas, Ensenada, San Felipe, Tecate, Mexicali, Puerto Vallarta, Mazatlan, and of course Tijuana (TJ!!!)
