Reclaimed Bluestone Sources???

Some years ago I heard from a guy who worked for the Trenton, NJ parks department about a large supply of salvaged bluestone sidewalk slabs that they had.  I actually got hold of one for my own house.  That guy has since been laid off as the city ran into budget problems, like so many other old cities.  But since they’re broke, they might be trying to sell some assets.  Not even sure who I can tell you to contact since all the people I knew there were laid off or have retired.  I bet if you just try calling some public works departments of older small towns you’ll hit paydirt eventually.
