Actually, some of us do have wifes like that. Every time I hold a Springfield M1-A and drool, mine says "buy it." Sadly, I never do...
I have to chime in as another with a wife who supports such things. Without DW, I would not be the owner of a firearm. She was the one who wanted to go hunting.
If I could only get her to run foredeck and bodysurf, I'd be all set.
