In 1978, the Caribou Ranch lent its name to a pro soccer team, the Colorado Caribous of the North American Soccer League. Co-owned by Guercio and future Washington state governor Booth Gardner, the Caribous were not a success on or off the field: they finished in last place, drew poor crowds at Mile High Stadium, and wore uniforms that many observers thought made the team into a laughingstock (brown and tan, with a strip of leather fringe across the chest). Guercio and Booth sold the club, after the 1978 season, to interests in Atlanta who renamed them the Atlanta Chiefs.
