The Weather Channel has been droning on endlessly about the incipient advent of genuine heat, and as the forecasts have grown increasingly dire, I've been mindlessly singing snatches of that famous Holland-Dozier-Holland classic "Heat Wave," a 60s Motown chart-topping hit by Martha and the Vandellas. And to look at the kitchen window thermometer, you'd be certain that the first truly torrid conditions have arrived. Of course, it isn't really that hot—the thermometer's in the sun, and it's one of those bimetallic models that are overly impacted by the sun's rays—but it's definitely getting up into uncomfortable territory... and slowing down terrain.
