May not be what you want to hear. BUT I would go somewhere you could just wander around. Keep moving. Kids don't like to be still. You may not do any good hunting, but he will have fun. If you want to have a hunting partner later, KEEP IT FUN! I about lost my boy at that age trying to keep him quiet and still hunting whitetail.
Oh yea. Keep them WARM and DRY, and FULL TUMMIES.
