ST. LOUIS, Mo. (KMOX) – Hope you have more than one green shirt — there are St. Patrick’s Day parades on both Saturday and Sunday this weekend.

The first is the big parade downtown at 11:30 a.m. Saturday, and the second the Hibernian Parade at noon Sunday in Dogtown. (Click to see road closures for downtown.)

John Buehlhorn, manager of Felix’s Pizza Pub at Clayton and Tamm, is hoping for great weather.

“If it’s good, it will be our biggest day of the year, if it’s bad it will probably still be our biggest day of the year with all the people who come down to see the parade,” said Buehlhorn.

In Dogtown, the celebration usually takes on a Mardi Gras-like atmosphere, lasting long after the parade is over. This year all businesses in the neighborhood will close at 8:00 p.m.

One reminder: the Dogtown Business Merchants Association and the Ancient Order of Hibernians have adopted a “no cooler” rule. Officials say the rule is in an effort to cut down on trash and underage drinking.

So parade-goers attempting to enter with coolers, backpacks or boxes of packaged liquor (beer, wine or hard liquor in cardboard containers) will be turned away.
