McCain's appeared Monday before an audience of several thousand bikers at the Buffalo Chip Campground during the nine-day Sturgis Bike Week, an event featuring bikers, many military veterans, rockers and off-color banners showing support for the Arizona Republican, Politico reported.
"Don't let November 4 find you on the open road," McCain told the audience. "I'm counting on you to show up."
Cliff Leach, a U.S. National Guard veteran, introduced McCain with a biker's view of an American utopia, the Washington political Web site said.
"We believe in a beautiful America. A land of beautiful roads, a land of beautiful bikes, ice-cold beers and a land of beautiful women," Leach said. "And that's the best hoo-ah a man can get."
