Take the boy for sure. I have a pop up blind and a carpet that I pack in so he has a place to play. Been taking him since he was 2 and he will quietly play with his trucks until there is something interesting for dad to point out.
At 4 he helped dad call in a bird for mommy and watched the entire thing.
Please PROTECT HIS HEARING if you will be using a gun in close proximity to him.
have fun,
later,
CS
