Random bits of lumber?

[teratomarty.livejournal.com]

Have you got bits of 2x4 or 1/2" plywood down in your basement or under the porch? Do you want to get rid of them? I'm doing some projects around the house, and I need a couple 3' lengths of 2x4 and a biggish bit of plywood (doesn't matter if the bits are bigger, I have the technology). Tags doesn't have anything sturdy enough, so I thought I'd see if anyone has semi-scrap lumber before I rent a Zipcar and haul out to Home Depot for two bits of wood. Thanks!

ETA: 9" square (or larger, of course) bits of plexiglas are also welcome.
