What to do with my bits and pieces

I have random old parts, including but not limited to:
-mini pumps
-road and mtb tires
-cables and housing
-random bolts, spacers, nuts, spokes
-usable chains
-a few old tools
-some schrader tubes

This isn't really hot stuff for someone looking to upgrade their ride, but rather good stuff for people who are throwing campus/commuter/beater bikes together, etc. Does CAT need donations of random but usable parts? If not, anyone know where I can pass them along to so someone can salvage them and find use?
