Perhaps you are right and almost all of my deer have gone down and died quickly but about 10 years ago in a raging last day of the season snow storm I went all alone to a wilderness tract of state land and still hunted a swamp. About 7 am I saw a medium sized buck about 100 yds away working into a wet area. I took the shot and saw he was hit but watched as he went over a rise. I tracked him down hill all day jumping him several times but was unable to get a sight on him. About 3 pm I was 5 miles away from the truck (all uphill) and finally got a chance to put him down for good. I gutted him and dragged him out to a dirt road I spotted on my GPS and finally had someone come along and gave us a ride back to the truck. The meat was darker than normal but it turned out to be a good eating buck.
