Anika MCauley & Laurie Vossler

Jefferson County Fair is gratefully dedicated to the memory of two longtime fair supporters, Anika McCauley and Laurie Vossler. Their spirited love of the fair and rodeo was contagious.

Anika McCauley was a talented teacher, artist, and Boulder Valley rancher. She taught junior high at Boulder Elementary and was many students’ favorite teacher. She was an artist who excelled at painting, creating wreathes, and many other arts and crafts. She enjoyed fishing, camping, and spending time with her family and friends.

Anika and her husband, Jim McCauley, organized the Boulder Rodeo for many years. Anika and her sister, Michelle Renskers, worked in the crow’s nest during the In-County Rodeo, timing events and keeping track of rodeo winners.

Laurie Vossler, beloved former owner of L&P Grocery in Boulder, enjoyed fair and rodeo activities. He was famous for bidding up baked goods at the Jefferson County Fair baked goods auction. His wide smile and the twinkle in his eye revealed it was all in good fun for a worthy cause.

Laurie was dedicated to his community of Boulder and generous with his friendship and help. He enjoyed ranching, working outside, supporting JHS sports, and his family.

Laurie Vossler’s and Anika McCauley’s smiles and steadfast support will be greatly missed at the Jefferson County Fair.
