Yes, he comes with me whenever he can. Unfortunately were I hunt, we don't see many deer after opening day unless you participate in deer drives or put in a lot of hours.
The higher chance of success, warmer weather, and feeling of having a season he can call his own is very exciting to my oldest son. My younger boy shows enthusiasm but is not old enough to understand fully yet. I also found out Friday that I have another son coming sometime around Christmas.
All 3 of my boys will be introduced to hunting.
