Celebrations are in full swing this weekend and ahead of what could be a wet and windy St. Patrick's Day tomorrow.
That's going to affect some of the events planned but the people at Draught Works Brewery in Missoula aren't worried.
They tell us they have plenty of room inside.
They are opening early at 10 a.m. and will give away free t-shirts to the first 150 people who come in.
Five different kinds of stout will be on tap to go with the Irish food.
Draught Works is also bringing in Irish performers throughout the day.
