Sounds like you are a duck hunter too? I'm not really into ducks but like watching the migration/seeing them - so follow at a distance -- there's a group Waterfowl Forums or something like that - they are facing the same issues -- what little I looked into it seemed that weather may have been affecting migrations - add on to that cheap licenses and not limiting people on popular public places (since we have so few pubic to begin with) and duck hunters are fighting over extremely scarce access.
RE the cedars - you can see the cedar invasion in the smokey hills and along Hwy 156 from I70 to Great Bend -- N of there -- it's starting - getting worse as the years go by. Smokey hills will be sad to see them deteriorate to a fraction of what they once were -- some of it has already happened.
The post above about one of the saddest stories is about right -- Im in the middle of building a house now and who knows I may not want to leave - but in the back of my and my wifes minds we dont plan on staying in this state - I want to go to NM, UT, NV, CO or AZ. KS can kiss my axx on the way out - Business is what is keeping us here for now, never dreamt I'd ever say that. In college/HS years this was the hunting heaven -- now not so much -- Wichita also is attracting sooooo many out of state Real Estate investors which is a passion of mine - nothing to buy even makes sense. Good for Wichita - but geeze - they're driving up the prices to farmland fundamentals -- IE farmland typically makes zero sense if you're getting a loan to make a profit on.
