Leftover conduit and drain pipe from a renovation is available for pick-up—we're a bit to the north of downtown San Mateo.  The pieces are a bit dirty from sitting outside for several years, but are otherwise fine.  No obvious cracks, and some slight bowing in a few pieces.  If you take some, please take all.  I'll help load.
