There are two holidays out here on the East Coast that are a much bigger deal than they usually are anywhere else in the country, including my section of the Midwest.
The first is Columbus Day, which is celebrated where I come from with a day off from work for public employees but not much else in the way of fanfare. Even most schools are open since fall break takes precedence. When I moved out here I was actually a little shocked at the pomp that accompanies Columbus Day, since many Native American people’s relationship with the holiday is understandably very negative. But Columbus was Italian, and a large number of Italian-Americans, also understandably, take a lot of pride in that.
The second is St. Patrick’s Day. Now, obviously St. Patrick’s Day is pretty widely and loudly celebrated in this country. Heck, there are more Irish-Americans than there are people living on the Emerald Isle. The Midwest is no exception. Irish-Americans are the most populous ethnic group in Chicago, and the Chicago River is died green every year in celebration of that fact. Another great body of water-dying tradition happens in my native Indianapolis: The White River Canal, which breaks off from the White River on Indy’s near-east side and runs all the way through the northern suburbs, gets its annual dose of green the Friday before the parade.
