Living and hunting in Colorado, it is my understanding that land does not have to be posted, just fenced. If you cross a fence, one side or both can be private, and can not be crossed without trespassing, i.e. private to public or public to private. If there is no fence or signs though, no harm no foul.
:thumbsup: Hi. I am new to this forum and I look forward to having some fun here.
Private property: in Colorado the landowner is not required to post their land; BUT, it is up to the hunter to know where the private/public line is and the landowner has the right to press charges on any tresspassers. Not easy at all! Being a landowner of a 40 against public land where there is a lot of elk hunting, I post my land and make it obvious to the hunter where the line is.
I think I would be careful with the no harm no foul statement. I do post my property. But I do know of others who dont. If you would happen to get caught they would run you through the ringer. Just my two cents.
I don't think private property can be hunted without permission in any state except in those states that permit so-called "road hunting" where birds may be shot if they flush from the road or its right-of-way. I believe South Dakota allows road hunting. When I took the hunter safety course in Colorado, great stress was laid on the hunter's responsibility to stay off private land regardless of whether it was posted. Posting of private property is not a prerequisite to preventing or prosecuting trespassing. In Kansas, if land is posted the game warden can issue a trespassing ticket without a complaint from the landowner if you do not have written permission in your possession. If the land is unposted, the ticket can only issue on the complaint of the landowner or person in possession.
