I also have a little history buff but mine is female. Among others we have gone through all consuming fascination with Ancient Egypt, the American Revolution and the pilgrims. As someone mentioned above we threw ourselves into each one - visiting every Egypt collection we had access to, touring Boston and Philadelphia and attending a harvest dinner at Plimouth Plantation - each at least twice. If you are uncomfortable with the weapon fascination - and I have to admit that I probably would be too but that's because I'm a total pascifist - I would gently try to guide him in the direction of a new area to throw himself into. You never know where it's going to come from. We got free tickets to a performance of the musical "Teddy and Alice" and DD fell head over heals for Teddy Roosevelt. An unusual passion for an 8 year old. And in our typical fashion it led to visiting the Panama Canal - twice. wink
