Two Dave Matthews fans got the surprise of a lifetime on Saturday while they were on their way to his concert in Hershey, Pa. They noticed a hitchhiker and when they picked him up, it turned out to be none other than the rock star himself. Matthews had been riding his bike before the show when he got a flat tire. He had left his cell phone at home, so Matthews had to hitch a ride. The good Samaritans got some snapshots, were upgraded to front-row seats, and even got a shout-out from the stage.
