When I started my car this morning I felt and heard a vibration inside the car. Looked underneath and this is what I saw,

I assume it’s all the slushy snow I drive through last night on my way home. I am just surprised that it was sticky enough to stay there and also not melt overnight. Also I don’t have a plastic cover on my license plate.

The high today in Southern Minnesota is in the 40's. In Northern Minnesota, it’s supposed to be in the 50's and 60's. WTF????
