Up in northwestern PA and it was chilly! But, I had a margarita earlier that afternoon...and man, what a great thing to do after a calorie-laden drink! First, you burn the calories off. Second, the alcohol doesn't make it nearly as cold as it really was (I'm thinking that it was 35-40 degrees....freezing for my little florida bones) :)
Now, I did list out all the items that you should consider having when running in the cold here....but seriously, alcohol could easily be added to that list!
