Allergies are trying to kick my rear end right now, so I wouldn't know if I got sick or not. I normally don't get sick from drastic weather changes though, so I should be good. We've already had 2 days in the 90s, and for it to be in the 50s is a shock, for sure! Better than my Dad's house in Oregon though. He had freezing temps twice last week. Had to break the ice out of the bird baths both times.
