I've been using DeerAge.com since the very early days thanks to my first taxidermist, who was an early adopter. He had some sort of connection to one of the founders that I've since forgotten. They've aged 5 of the 6 "older age class" bucks I've killed and as a guy who hasn't killed anything huge, the validation of age has been the thing I could hand my hat on. It's awesome that you took the time to do this and even better that it was a great result! Congrats again on a damn fine whitetail!
