Danny , ur in for some good times. My daughter had her 1st sit in a stand at age 5 an it went well.I set climbing sticks up because there safe an brushed in the stand real well,if you can see the deer before they get close it makes it a lot easer an i bet ur son will be quite as mouse. My daughter aslo started gun hunting at 7 an bowhunting at 8. The biggest thing is keep it exciting an keep the hunts short. One of the things i do, an its legal in my state is i set up a special stand(2 sideby side) just for my kids an i bait it really hard, so when we sit it, its a lot of action. I no baiting is a hot topic but if that helps keep my kids interested in huntin so be it. It allways seems gust when u think they can`t,they WILL, so don`t underestimate their age. I have also used blinds as well, i set 1 up in sight from my house an my daughter would set it after school(by herself whick she thought was cool) an do her home work, nothing is cooler when u get the call on radio that she sees deer coming her way.I really think the younger the better. Last tip TAKE VIDEO becouse they grow up fast!
Take him now and as often as you can. Let any boy or girl know you're more interested in spending time with them than killing something and chances are you'll have a hunting partner for life.
I CAN`T SAY ANY BETTER THAN THAT
