I started hunting grouse 50+ years ago here in western , N. C. I have noticed a definite cycle down, down, down, In my early years plenty of grouse wouldn't consider traveling to hunt , zero Turkey population, Turkey introduced now almost zero grouse population . Started hunting U P and Wis. before I saw any Turkey' Grouse hunting great, started seeing turkey Grouse flushes down about 1/2. Just my what I've seen in past 50 years in areas I've hunted. So here I am with the best dogs I've ever owned and no birds to hunt!
