My son also got his 1st deer this year. It was a doe that weighed about 80lbs. Bet you were like me, grinning ear to ear slapping him on the back and shakeing the hell out of him, lol.
Deer Whisperer--you bet we were! We were high fiving and slapping each other on the back and huggin' I was happier for him than I usually am about the ones I get. I was the same way a number of years ago when my oldest son (who was also 14 at the time) took his first -- an 8 point with the bow that scored 128 P&Y!
I've taken 4 myself this year, but I'm limiting myself to bow only -- again.
