After promis­ing myself (and the dog) that we would get our deserved 30 min­utes of exer­cise, I came home last night, changed into the appro­pri­ate clothes and got out­side. The weather’s been unsea­son­ably warm. I know, I know. Global warm­ing, we’re all gonna burn, but it was dark and still 75 or so. As we approached the park I could feel lit­tle cold spots, like the ones you feel in a poorly heated house (or, say, my home) but they were small. My lower body was fine and warm and then my arm would sud­denly get really, really cold.

OK, or maybe there are just ghosts in the park.
