At some point it's just bones. No smell.

Almost every year I go to the Hudson-Meng Buffalo kill site in Ne. Its a display of a buffalo kill site, no clifts there so I dont know what happened. They have a building over the site and charge admission. Just saying. Buy the site and make up your story, they will come.
The reason I go there in Ne is because I have killed several good mule deer within a mile of the site.
