Gov. John Hickenlooper, Colorado Agriculture Commissioner Don Brown and History Colorado executive director Steve W. Turner are jointly saluting some of the Colorado’s oldest family farms.

Thirty-eight families who have owned their farm or ranch for 100 years or more will be honored at the Colorado State Fair in Pueblo on Aug. 25 at  4 p.m. in the Colorado Building at the fairgrounds.

The event marks the 31st year the state has honored these vaunted Centennial Farms.

“These farming and ranching families have withstood the pressures of difficult weather, state growth and changes in the agricultural industry to preserve important pieces of our state’s commercial and cultural history,” History Colorado said in an announcement Friday.

The farms will get one of those metal Centennial Farm  signs to put on their spread.

This year’s class brings the number of inductees to 550 Centennial Farms and ranches across the state.

Here are they are with the year their operation began and the nearest town or community with the county:
