In my neck of the woods, the only things that celebrate Columbus Day is the government (no mail, no courthouse (and offices), majority of banks are closed). Everything else is open. Including my daughter's college which I am taking her to in the next few hours for her finals.
My town doesn't do anything, but they suck anyways. We don't have anything for 4th of July here - they rely on neighboring (smaller) towns to provide the festivities so they don't have to. We have a strawberry festival every year (we are a strawberry farming area) that only has 10% to do with strawberries. Like I said, this town drops the ball on holidays.
