I'm planning my first trip to SD for this fall/winter and aside from knowing it'll be a pretty big waste of time, [2-3 guys, no dog, and public land] what part of the season would be considered the least waste of time under our conditions? I'm considering any area from the SE corner up to Chamberlain, coming from Missouri and want to keep the drive 12hrs or less. Info on early, middle, or late is all I'm after, not internet scouting.
