One fellow I know went to Maine last year...Over 100 flushes in three days.
Pheasants???? DuxDog here has a place in S.D. to stay and he feeds you well...it would be worth looking into if you want to hunt public land on your own and have a Dog....A friend of his has helped us out on finding spots..Seeing 100 to 200 Birds a day isn't uncommon. They can be on the wild side....but they screw up often enough...Hell, one even flew into a telephone line and killed itself....
And it wouldn't be rare to find a few nice shotguns hanging around also...
