SW Nebraska has some spots of public that aren't very big but have loads of Merriams . The black Hills in South Dakota have a bunch of birds and lots of land . I can give you some places to go in either state where I've killed Merriams . Don't over look sw Colorado in the San Juan's either , lot of birds if you know where to start looking .I'm working on mine, all I have left is the Merriam's. If I can find one on public ground, I will have got it done all on public ground.
