IMO the best league. I root for a local team. The team of my birth City, Veracruz; Los Tiburones Rojos de Veracruz. Outside Mexico I like La Bella señora de Turín, La Juventus.
Regarding my first major league game it was last year. It was at Yankee Stadium. Boston won. It was one of my greatest expiriences ever. Loved the environment. You can see a lot of families, thing that these days is hard to see in fútbol games in Mexico or South America for instance. After that series in NY I went to the home opener game against the Nationals in Fenway. We won as well. Then I went to a couple games against BAL after the series against WSN, and we won as well LOL!. I was very lucky, we won in all the games I went. The environment in Boston is just spectacular. A lot of beautiful women in both parks LOL!. I will try to go in August again, but this time with my wife and little baby. Last year I went with my best friend who lives in Boston and his girlfriend and a couple of friends of her. I had the opportunity to visit several bars outside Yankee stadium and Fenway park as well. It's worth to mention that I made a lot of friends LOL! People in NY and Boston were very nice with me. I also had the opportunity to visit several restaurants, Btw in both cities you can find great rest. Definitely is a must go every year.
