CANCELLED - Lancaster Amethyst - CANCELLED

This trip has been cancelled.


Dig on the Upper field (NOT same one we were on last year).  Since this is the same day as Diamond Mountain, we will run BOTH trips, and the Amethyst Trip will be split with some PESA folks that day.  We can have up to 25 - 30 of us (shared with FM-NJ too) for the Amethyst trip.
