Columbia Falls marks the 100th anniversary of its incorporation this weekend at Heritage Days 2009.

"Celebrating Our Centennial" will be the theme from the opening of the farmers' market at 5 p.m. today until the last ball drops into the cup at the Wildcat Endowment Golf Tourney around midday Sunday.

Two nights of rodeo, the ever-popular fireman's breakfast, a Saturday noon parade, a wild horse drive, and a line-up of dances will help fill in the fun for the rest of the weekend.

As a bonus, Columbia Falls Swim Team will host 400 to 500 competitors at the Western Divisional Swim Meet at Pinewood Park pool Saturday and Sunday.

This year's Heritage Days buttons, at $1 apiece, include four mystery buttons that will be worth $100 gift cards at Super 1 or Smith's grocery stores, or $50 gift cards at Mike's Conoco or Town Pump.

Buy them at just about any Columbia Falls business or at Saturday's information booth. This year, you need not be present to win.
