Your welcome from the D.C. Chapter.
We're not sure which is worst, cold driving rain, freezing weather or 90 degree heat.

Having been out in all of the above the worst I can remeber is the time I was hikin in freezing rain. The problem with cold rain, is the risk of hypothermia. The cold is not a problem if you dress properly, however it gets so hot in DC that it is difficult to dress properly, as you sweat standing still in only your underwear.
