A squeaking & hissing radiator is a sound I haven't heard since my sophomore year in college (or before, really), but there they go. Over the weekend the temperature dropped about 20 degrees--it was a "brisk" 45 degrees this morning when I drove Robin to campus, warming up to the mid-50s but now cooling again. Plunging my arm down where no human hand has gone in a year (hint: roll sweater sleeve down, not up) to see if I can turn the knob and nudge a little more steam out of that sucker.
