I hear ya---I felt that same pain on Tuesday and Wednesday when the DC metro area was having spring-like temps. Irony of all, I called in sick to work because I have the flu, so even though I was at home, I felt too lousy to ride (still feel lousy). Try to think on the positive side: you don't have this awful bug that's making the rounds and if you bundled up a little, you still could get out there.
