Alright, we have about 50 votes between the two sites I posted this on.
The average of the 50 votes was 5.55", the median 5.5".
The longest guess was 7.5" and the smallest guess was 4".
There was almost no deviation between the two different sites; AZ Hunter had a 5.52 average and Hunt Talk had a 5.57 average.
The official score of this buck is 97-4/8" SCI and the buck currently ranks #2 in their record book.
If we use this SCI score and use the buck's left prong (the closest one to us in the photo) then I guess we could say that NOT A SINGLE PERSON guessed the prong length correctly. The buck's left prong is listed in the SCI record book at 7-7/8".
I think we can also safely say that if this prong is 7-7/8" then I'm Ronald McDonald!
