I haven’t hunted bear, but I have lived in bear country for my whole life. I would say a black bear is doable, not very doable. You’d think they were around every corner by myth, but it is a worthy goal. Elk, mule deer and antelope are very doable in WY, but you will find antelope more challenging than you might think, especially with a muzzleloader. If you choose to accept the hospitality of your friend, the lion hunt will be the jewel of your stay. I watched/heard hounds tree a cougar in the Jemez Mountains of New Mexico and it stirred a longing within me that I didn’t know was there and spurred me to begin hunting with dogs. I would invite you to my hunt, but my style is not conducive to what many consider “successful” hunts. A lot like hiking with a gun. If that suits you, you are welcome. The animals here are amazing, but the land is epic. Cheers!
