Tom Mayhew sprays lubrication fluid on a bicycle June 7 in the basement of St. John the Evangelist Church rectory in Green Bay, Wis. Mayhew, a retired dentist, was homeless and turned to the shelter after his practice went bankrupt. Now back on his feet, he says repairing bikes is a way for him to give back to the shelter.
