I let a few 1.5 year olds walk this year. I also let a couple of 2.5 8's walk. The 2nd 3.5 year old I saw got the shaft. The first 3.5 I saw I got busted by,He caught me off guard. The way things went this year I couldn't be happier but I was going to try and hold off for a 4.5 or better but time constraints limited my hunting season.
