Please request permission in advance from the land owners before you cross or hunt their property.
If you are starting at your property near Fairplay, you can go to the Park County Assessor's website and start tracking the owners around you from those records and maps.
By contacting the owners, you will also be meeting your neighbors.
Treat them the way you would want others to treat you and your private property.
I have rarely heard no when I asked.
When there is a no response, it is usually because they have already given permission or are hosting other hunters at the same time.
Good Luck with your hunt!
