My game warden experience, and not one I'm proud of, was maybe 25 years ago with a group in SD, annual trip with a few friends and one guy had some relatives out near Wessington. We would typically go the same weekend annually and back then, the daily start time was Noon, and would reset to 10:00 after daylight savings would kick in. I don't recall the reasons why, but we moved our trip up a week and got into the field at 10:00 and had a lot of shooting and bagged several birds right away. We take a break after the first field and notice a truck pulling up and realize it's the CO. He gets out and explains to us the season doesn't open until Noon, writes each of us a ticket and takes all our birds. Boy did we feel stupid. I think we all pooled our money together and paid the fine right there on the spot, in cash. Total blunder and embarrassment. A bunch of guys in their 20's that were so excited to be out there we completely forgot about the Noon start time early in the season.
