I've only killed one elk with an arrow. It was back on August 14, 1973, the opening day of the Colorado archery season. I lived in Steamboat Springs then and was hunting just outside of town with my Herter's recurve bow, fiberglass arrows and Bear razor insert broadheads.
Three bulls were feeding in my direction through the oak brush, so I just knelt down, let the first one pass by, and made a 10 yard shot on the second one. Just a few minutes after I shot him I heard the noon whistle in town. I sat right there and ate a sandwich and waited 30 minutes before I stood up. The third bull had stood there out of sight until I stood up, then he ran off through the brush.
It took me another half hour to find my bull. I gutted him there, but did not quarter him, but I did prop his rib cage open to let him cool. It was probably around 3 pm when I got back home, and close to 6 pm when the landowner showed me a way to drive my truck right to him. When I got him home I was able to hang him from a large cottonwood tree.
The next morning (Sunday) I quartered him and was able to hang the quarters in a friend's cellar. The next afternoon my friend called me to get "that stinking thing" out of his cellar. Evidently the side that laid next to the ground had not cooled and had soured and spoiled.
That was the last time that I archery hunted in August, and the last time that I've left an animal on the ground for very long.
Every time that I see a hunting TV show where they shoot an animal, then wait until the next day to look for them, I'm sure they will find a spoiled animal when they do find him.
