Did you guys even look at the dates on the pictures?
The first buck is 1.5 years old in the first pic taken on 9-27-2006 and there are 4 consecutive years of pics of this deer making him 4.5 years old this year.
The second deer, judging from the antler mass, looks to be a 2.5 or 3.5 years old in his first pic on 11-28-2007 and there are 3 years of consecutive pics which would make him 4.5 or 5.5 years old.
