Never heard of any! I broke my tradition of going out of state and watching it on CNN in a hotel room because I was too sick to make my flight out. My dad came in though so I still spent it about the same way. I really don't see the big deal, time is continuous, we just make up units of time to stay sane and function as an organised comunity, I don't really think it should be a holiday but that is just what I think.
