Hey cliff!
I know what you mean about alot of firepower! My 'navy' is currently twice the size of the US Navy!
I also have quite the large collection of Aircraft and Armor as well, all in 1/72 scale. If you want to see some glimpses of some of my collection, check out the "Small case of insanity" Thread!
I look forward to seeing pictures of your collection. And don't worry, most of us married guys relate to your wife's difficulty in understanding you love for this hobby. Then there are the lucky few who's wives steal their kits to build for themselves....
