Volunteers wearing navy polos and hats emblazoned with the phrase “street pastor” fanned out across Bangor’s Davenport Park last Friday afternoon, armed with water bottles and lollipops. Roughly 30 homeless people were scattered throughout the park on blankets and chairs, and the six members of the Greater Bangor Street Pastors made a point of stopping to speak — and listen — to each one. Many of the conversations were brief; others were longer and sometimes meandering.
