Proof that the U.S.-Mexico relationship may be in trouble

Relations between the U.S. and Mexico, while usually good, have been a bit strained lately, mainly because the Mexican government feels that it has been getting the short end of the stick in recent months in terms of immigration policy and the fact that Americans have been warned not to vacation south of the border for safety reasons. Now this - the announcement that the National Football League will play a regular-season game in Mexico City in October, the first time an actual, it-counts NFL game will take place outside of the U.S. Fine - except the more the 100,000 fans expected to pile into Azteca Stadium will get the privilege of watching two of the worst teams in the league - the San Francisco 49ers and the Arizona Cardinals. The Corona beer had better be half-price that Sunday.
