This June 5, 2012, photo shows truck driver Michael Siau after he was reunited with his dog, Rambo, in Hannibal, Mo. Siau was en route to North Dakota and made it all the way to Cedar Rapids, Iowa when he realized Rambo wasn't in the back seat. Rambo waited at the rest area where he was mistakenly left until Siau's truck route sent him back through Hannibal to pick him up.
