We lived in Northern Virginia in the 1970’s. In ‘76 my husband voted for Ford and it pains me to admit it but I voted for Carter. I dragged my family to Carter’s inauguration. We nearly froze to death. It was all downhill from there.
The weather at that time of year in D.C. is usually terrible. It's always cold and often rainy, windy, or snowing. For Bush's inaugural I went to West Marine beforehand and bought a set of marine rain gear, a yellow parka and pants, and Polartec everything, and that with a pair of Sorrel boots kept me dry and warm all day. I would recommend wearing something like that.
