Welcome to the forum Johann! I have never hunted in those areas that you mentioned but have looked at them on the land owner status maps quite a lot. There isn't a whole lot of public land that's huntable for antelope in those areas. What public land is available or accessible is in small patches. I hope someone on here will chime in with some better help, or PM you with better info. My advice in your situation would be to try and find an outfitter that would take you out hunting on privately owned land. Best of luck and enjoy your trip!!
