Boston's St. Patrick's Day Parade is the second largest in the US, at least according to Wacko Hurley.

New York's is the biggest, no arguments there. But Holyoke is claiming to be number two, ahead of Boston. Not likely. A more legitimate claim to the second biggest parade comes from Savannah -- yes, Savannah Georgia -- where they go all out with their St Pat's parade. (They certainly have a better parade website than Boston's.)

Although we're probably not number two, we do have bragging rights. According to Wikipedia, Boston's parade was the first ever, held in 1737 and organized by the Charitable Irish Society.
