Country artists were among some 1,000 bikers, about 40 of them people in the country music industry, who paid $30 each to take part in the ride which began at the world's largest Harley-Davidson dealership and toured up nearby Mt. Charleston before ending up with a 7-hour concert at downtown Las Vegas' Fremont Street Experience. The ride included Dierks Bentley, Eddie Montgomery and Troy Gentry of Montgomery Gentry, Ira Dean of Trick Pony, Rockie Lynne, Keith Urban, Little Big Town and Big Kenny of Big & Rich.

Keith Urban saddled his chopper, but brushed off a request for a comment with, "I'm just here for the ride, man." Urban is not giving interviews this weekend following the announcement by fellow Australian Nicole Kidman that they are engaged.

Dierks Bentley, another veteran biker, called the chance to ride and to do it for charity "a cool deal." Bentley and Urban are up for top male vocalist at Tuesday night's awards show (8 p.m. PDT on CBS) and Urban is a nominee for entertainer of the year.
