Heat is the main problem here as well. It' s the main reason I' ve gotten so picky about shot selection. If I shoot one in the evening, I' ve got until about 2 hrs after daylight the next morning before they will be covered with blow flies and or buzzards. Late November and December, I have a little more time, but not much. That' s the main reason I want a perfect double lung shot every time. Fifty yards and they go down and I can go get the 4 wheeler.
