I love it! That is, if you're talking about the movie with Bill Murray. In fact, it's the only Bill Murray movie I like at all. Every other movie he's just too much of a cad or a buffoon. In this one he becomes a character that I give a sh*t about.
But as a "holiday", it's never made sense. I grew up in north central Minnesota, still live in the state. Six more weeks of winter, here, is a reprieve, not a sentence!
