Too bad Mexico has already laid claim to Cinco de Mayo on its calendar, because that country doesn't do anything to celebrate the alleged holiday — whereas here in the Mile High, May 5 is a party worthy of celebration. One weekend a year, generations of Denver's Latinos head toward Federal Boulevard in their lowriders and whips, rolling on fat chrome wheels or bouncing on hydraulics with traditional gold spokes. The result is a cross between a car show and a parade. Some vendors peddle Mexican flags — even though half the people who come out to celebrate were born on this side of the border — while others sell tacos in the street. Teenage lovers hold hands, parents push strollers and point out the pimped-out cars to their kids. Aside from a couple of knuckleheads, the festivities are usually peaceful, and Denver makes sure there are more than enough police officers on hand to make people feel comfortable — or uncomfortable, depending on who you are.
