I'm from Illinois-- we get Casmir Pulaski Day. I like seeing the regional differences.

I think part of the reason many colleges are moving toward a March break is the move toward a May term. You can't end classes in late April and have a break right there. March is better suited-- everyone has been there a long time, people are starting to get antsy, and if your climate's right everyone will come back and the campus will have bloomed.
