What happens if a member encounters a trespasser or another member on the property without a reservation?

In the event that a member discovers a trespasser, they should avoid the person, and if at all possible we ask that you get a photograph of the license plate of the vehicle, and call the emergency number. Should they not answer, please call 911. Colorado Outdoor Sports and local law enforcement takes this VERY seriously and will prosecute trespassers to the fullest extent of the law.

If you discover another member on a property without a reservation, please report this to the club.  Members hunting/fishing/camping without a reservation will be disciplined or expelled from the club.
