Doesn't hunting good private land kinda defeat the purpose of going for a challenge. If a group of 5 can limit out in 4hrs with any kind of consistency in the late season it makes me wonder where the challenge is.
For me, having bought a 1/4 section in SD back in 2000 and having it totally set up for wildlife habitat, it simply ensures that when I take time off of work and drive 8 hours, I don't have to worry about someone else having just shown up expecting to hunt the ground I intend to hunt. I also hunt public land over the course of a multi-day hunt, and, other private land that we pay (minimally) to access from the farmer who owns the farmhouse that we stay in. It is easier, obviously, to go shoot a limit of birds on private land vs. public. Some guys object to paying to access land...some guys can't afford to pay to access private land...some guys give fairly spendy gifts to landowners who let them access their private land...some guys hunt public land only....some guys hunt ditches...some guys roadhunt...some guys shoot their birds out of truck windows....as far as I am concerned, as long as you are doing it legally, and safely, enjoy your hunt and if you have a few extra bucks, join Pheasants Forever.
If you have the luxury of hunting midweek, the public vs. private debate changes a bit. And, If you have the luxury of waiting until the last minute to schedule your hunt, that debate changes even more. But, if you are forced to schedule your hunt months in advance, and you want to stack the odds in your favor, going the private land route makes sense. Why else would fisherman go to Canada when they are driving by thousands of decent lakes as they drive North out of the Twin Cities? Seeing large amounts of game is thrilling to many people, myself included. I appreciate a single flush perhaps even more than a 20, 40, or even 100 bird flush, but the big flushes are an experience. Just watching hundreds and hundreds of birds move from the corn into their roosting cover in the late day is something I never get tired of...I still get loopy when I see that!
If more shooting vs. less shooting is what turns you on, by all means plan your hunt accordingly....I think Kansas is at 4 per day. I have taken advantage of the ND rules on a few occassions so I could hunt from 1/2 hour before sunrise, then cross over to SD later in the day and work on my SD limit...yes, it was about increasing time afield (read: more birds!). Bottom line, enjoy your hunt, be safe, and do a little something to preserve this sport.
