Scavenging is the orginal form of reuse/recycle that happens when you are thrifty (read: broke). I got these SWEET casters from my neighbor to help with the first moveable wall and some other leftover building materials as well: glassblock for repairs, leftover drywall and studs. These will definitely give us a jump start on the first couple of weeks...we may not be tent city for as long as I thought.
