Frederick, Maryland - One recent Monday, the line in the Church of the Brethren parking lot began to form at around 2:30 a.m. when a husband and wife arrived. They came almost 8 hours early in the hope of seeing a dentist - for free.

    They soon watched the headlights of other cars as they pulled into the lot. Some would-be patients laid out blankets and sat on the pavement to wait for hours so they'd make the top of the walk-in list to see a doctor or dentist at the Mission of Mercy traveling clinic.

    By the time the clinic, a converted recreational vehicle, opened its doors and the church's multi-purpose room became a waiting room, a nursing station and a dental office with blue dividers and folding chairs, more than 100 people had assembled.
