L-R: Bones star David Boreanaz; rock legend, entrepreneur, tequila aficionado, owner of Cabo Wabo Cantinas and soon to be Rock 'n' Roll Hall of Famer Sammy Hagar; and California Speedway President Gillian Zucker meet with driver Kevin Conway on Saturday, February 24, where Hagar was the grand marshal of the Busch Series Stater Bros. 300 race. Hagar, of course, started the race with the famous three word phrase, "Start your  engines!" Two nights before, Hagar rocked the house at Fontana's Racefest as the featured performer singing five songs including his famous "I Can't Drive 55," on Thursday, February 22 in Fontana, CA. Photo by Jill Weisleder/California Speedway.
