I have done this contest for 5 years now. Seems to be less and less hunters every year. This is probably the #1 reason.
Some of the picture I see show nothing of the score of the bird. If I shoot a bird that scores in the 70s or 80s, you are gonna get good clear pics to prove it. Most pics have a bird by a tree on the ground or pilled up in the back of a truck. You can not see a beard or the hooks.
This is an " honor system" contest. We can only hope people are telling the truth.
I do believe to make the contest better and fairer in the future, clear pics with tape measures should be required. Maybe even some way to prove the dates of the harvest, this is suppose to be a Spring Turkey season contest.
