Yes he's definitely 3.5 yrs old. I have a pic of him last year and you wouldn't believe the growth. He added 30 inches easily.
Theres also a 140 inch 9 point that is out there. He's also 3.5 yrs old. I will have a tuff time passing him if I get the chance. Either way one of those bucks will make it to next year unless some chump slug hunter gets lucky on a drive. But thats highly unlikely.
