I live about 6 hours from Cobalt, Ontario, where it is pretty easy to
find erythrite specimens, most of which are pink crusts on cobalt and
nickel minerals (although I have one piece with needle-like crystals).
I was there last fall and collected lots of erythrite.  I'd happily
trade some Canadian erythrite for some meteorites...
