I hunted turkey hunted in Nebraska 6 or 7 years ago. I wanted to kill a mature Merriam's. I had killed a jake in north Dakota but needed a long beard for my grand slam. We hunted the north west corner of the state in a place they pine ridge. We hunted on public ground and there where plenty of birds. The gobbling was great we located birds everyday we where there. we both killed mature birds and had a great time. Camping was free at the area we hunted I can't remember the parks name.
if you hunt in the eastern part of the state you will find easterns not Merriam's
