There is great value in knowing game laws because the CO's don't always know themselves. Case in Point: My Dad is a MN resident, he bought a NR Pheasant lic for SD when he came to deer hunt in Nov. SD NR lic are good for two 5 day periods. We also have a family friend who has a farm that is a licensed preserve. This weekend that friend has a get together and there are 13 of us. The Gamewarden stops by and does a license check. The other NR all have SD Preserve Lic. My Dad has his regular NR Lic and it isn't one of the five day active periods. CO takes my dad into his pickup because he says he is illegal. I very politley ask him to do some checking because a NR lic is good for two five day periods and on a preserve for the entire season. The CO doesn't think so. We leave my Dad with the CO and continue hunting. After 30 min or so the CO brings my Dad over to where we are hunting. Yep I am right he was wrong. He called another CO and then had to call his boss after that. He was a nice guy and just doing his job, but if he hadn't listened to the request to check into it before writing the ticket he would have just wrote the ticket. The only thing that bothered me is Lic requirements are pretty basic and a CO should know those inside and out. I do commend the guy for checking into it he was a very nice guy and we all understand he is just doing his job. It probably helped we kept everything very civil and polite.
