Saint Patrick's Day has always come with a lot of alcohol. Josh Griffin, general manager of Tin Roof, said they stock up for it.
"Just for today specifically I mean we had four or five extra kegs and 20 extra cases of different types of beer," he said.
Police have prepared for it, too. Metro Nashville traffic section commander Lt. Michael Gilliland said they'll be conducting sobriety checkpoints.
"We're looking for anybody making the poor decision not to use designated drivers," he said.
And they want those drivers to be on the lookout for pedestrians who might've had too much to drink. Gilliland said drunk walking can be deadly.
"Last year we had 17 fatal accidents in Nashville involving pedestrians with a total of 18 pedestrians killed," he said. "Seventy-two percent of those pedestrians were intoxicated."
That's why authorities said it's very important to obey the crossing signs and have a plan before you party.
