Happy St. Patrick's Day

There is some confusion as to when the St. Patrick's Day falls this year. Was it on March 15th or is it today March 17th?. Quoting from CNN

For the first time since 1940, St. Patrick's Day will fall during Holy Week, the sacred seven days preceding Easter.

Because of the overlap, liturgical rules dictate that no Mass in honor of the saint can be celebrated on Monday, March 17, according to the U.S. Conference of Catholic Bishops.

However in Ireland March 17 will remain an official Irish day off work and the Dublin parade will go on as scheduled.

So today being St. Patrick's Day (for some March 15th), I decided to take a look at towns and cities across United States named Shamrock or Dublin. There are 19 cities/towns which I found at the United States Government Census site. Here's a look at those towns/cities on Google Maps.
