On my pre-dawn hike up and down Granite Street this morning, wearing my reflector vest with the flashing red lights, I felt like I fit in perfectly with the celebratory atmosphere of the season. I was a lit-up, walking Christmas decoration in the early darkness of this Christmas Eve morning. I especially enjoyed passing one particular house at the top of the hill, because its holiday lights strung along the eaves seemed partners to my brightly blinking vest. The entire walk was like a festive occasion. I can’t recall ever exercising in a merrier way. I felt like my glowing vest was a Christmas ship cheerily carrying me along.
