I was incredibly frustrated the first time it failed, not because it failed, but how and why. I was living in Springfield and getting a biology degree. I also spent a great deal of time hunting, hiking, backpacking, and floating in the Ozarks. We spent a great deal of time on the real issues of habitat, competition, property damage, etc...
But none of that mattered. What mattered was that people were trying to bring change to Missouri, and that was both horrifying and ridiculous.
Cattle and elk can co-exist. I've killed 3 bull elk on ground they run cattle on. Elk and deer can co-exist (and the deer herd quality has never been great in the Ozarks anyway). What moderate amount of whitetail hunting opportunities that are lost would be replaced with an incredible opportunity to enjoy elk in wild country, for a demographic that may otherwise never get to experience that.
How incredibly cool would it be to camp on a gravel bar on the current in September and be able to listen to elk bugle? I'd schedule a float the first year they were released.
