I missed this earlier in the week. Apparently St Patrick’s Day marks the anniversary of the creation of the City of Niagara Falls, New York…
From the Tonawanda News:
It’s the day when nearly everyone is Irish but there’s more than just St. Patrick to celebrate here on Sunday.
In addition to paying tribute to the patron of the Emerald Isle, it’s the anniversary of the City of Niagara Falls, chartered by New York state on March 17, 1892.
