Caleb Blakeley, 12, of Marcotte Street in Lewiston shoves off after giving a big push to get the “MC Mobile”going in the parking lot of the Colisee in Lewiston Tuesday afternoon as his friend Mike Sawyer, 12, of Summer Street in Lewiston steers. The “MC,” which stands for Mike and Caleb, was built from scraps of disgarded material they found around the neighborhood and held together mostly by string and duct tape.
