I hunt on two ranches close to home for whitetail & mule deer. Both ranchers have given me verbal permission to hunt there land anytime. Last year before season started, I again confirmed permission with both ranchers. I gave both rancher a 4"x6"-card.
The card had all of my personal information on it. License plate number, truck color, hunting license number, home telephone number, physical address & mailing address. I could be wrong but I think they both like having this information? They both know they can reach me if there is a problem.
