Best one I ever had mostly froze in a blizzard the night I took him, then hung in my garage for 12 or so days with the hide on at 45*.
The next best didn't even age, we started eating on that one the night of the kill.
So you've shot 2 elk so far. LOL.
Worst meat I've personally had was right after a kill nad put on the grill. Tenderloins of a young deer. HORRIBLY TOUGH
