It depends on your expectations and how hard you're willing to work as far as scouting goes.
The thing about these areas is that there are thousands of hunters trying to hone in on where the dogs are. Therefore, anything that's easy to get to find/get to is going to get shot out by locals first and then by dozens of tourist shooting parties.
Also, you have to have the equipment to access areas in the prevailing conditions. The last 5 years have seen summer rainfalls of record levels leaving vast areas inaccessible to most vehicles due to "prairie gumbo". You have to have the equipment that is capeable of getting you OUT of anywhere you get into should you get stuck or get out in dry conditions and then have a t-storm turn the roads to gumbo.
If you expect glowing hot barrels and busting out 300+++ round days one after the other, you're going to be disappointed.
If you're willing to do a LOT of driving and scouting and put up with the fact that on average you'll be lucky to shoot 50 rounds a day, there is hunting to be found. That's an average, so on some days you'll fire 0 because you'll spend all day scouting and it'll all be for nothing.
I've done a lot of hunting on Buffalo Gap and after a number of years where you've built up a milk run of decent spots that are hard to access, you can have some shooting. The key is that if you get complacent and stop scouting, your shooting will quickly disappear as towns get shot out, plague wipes them out, or other parties hone in on your spots.
The bottom line is that despite vast areas of accessible land, the shooting on average is very poor and it takes long/hard work to find your own spots.
