From the Roast and Ride Rally: "The annual event is a slice of pure Americana. When a young pastor offered a prayer from the back of a pickup truck outside a big yellow barn owned by Harley-Davidson, bikers removed their caps, placed them over their hearts and bowed their heads. The convoy rode in staggered formation past churches, suburban houses with clipped lawns, shopping malls and rolling farmland to the Iowa state fairgrounds.

Mike Pence, set to make his entry into the primary official next week, was the only White House hopeful to actually take part in the charity parade. The former vice-president, who turns 64 next week, rode a cobalt blue bike and wore jeans, boots, a white helmet and a black leather vest with patches that said “Indiana”, “Pence”, “rolling thunder” and messages supportive of the military."
