If anyone was wondering: Yes, there are a lot of illegal immigrants trying to cross the border from Mexico, according to this news from the Department of Homeland Security:

Since DHS kicked off the Arizona Border Control (ABC) initiative March 16, 2004, agents have made more than 351,700 illegal immigrant apprehensions at the Arizona border -- evidence of substantial progress at securing the border against illegal incursions. Prosecutions of human smuggling organizations, another key indicator, have increased by 68 percent. Migrant desert rescues have more than doubled, potentially saving 697 lives. In addition, narcotics seizures have risen from 165,057 lbs. in 2003 to 359,604 lbs. during the same period in 2004.

That's almost 2,100 illegal immigrants per day - just along the Arizona border. (Or, in total, the same number of people who would fill six, sold-out games at Yankee Stadium.)

And a lot of drugs.
