Man, that looks JUST like the one I passed on opening day in Mazama...was it around there?! Congrats on his first buck, I am sure he is very thrilled on a very fine buck!
PS...the only reason I passed was I had packed in, stayed the night and it was the first buck/deer I saw that morning, I was expecting to see something a bit bigger...but got skunked. Never pass on the first day, what you would shoot on the last I guess!
Again, congrats to your boy, he put a fine shot on it.
