I think it would be fun to see other folks' wood collections/stashes/hoards. It seems we all here are afflicted with the same disease, we might as well show it off! I'll get the ball rolling.
Here are some quick and dirty pics of my 'lumber room'. The room is adjacent to my basement, and adjacent to my shop. Ok, the lumber room is really just part of the utility room where my furnace and water heater are, but that doesn't sound nearly as cool. It is a fairly good-sized room. My shop is directly underneath my garage (it is a spancrete garage), and is accessible from within and from outside the house. As you can see, I have a section for blocks, a section for irregularly-shaped pieces, a section for lumber, a section for red oak, and a section for white oak. The red and white oak boards were both milled from trees on my property. The white oak is from the trees removed when I built my house back in 2004, the red oak (the only red oak on my property) is from a tree that came down in a storm earlier this summer. There was a bit of rot about 20 feet up in the red oak, and, as I learned, a family of raccoons calling it home. All the white and red oak is quarter sawn. You can see in the top of the lumber picture there is a shelf where I keep several hundred square feet of my larger sheets of veneer. My long sheets of veneer are kept elsewhere.
Let's see what you've got lying around...
It's a whole month before we move. And it'll take a while to get the new shop set up.
That should keep you busy for a while!
