Dietmar Popp and Anne came all the way down from the very northeast of Germany at the Dutch border. They drove all night. Dietmar is the expert who makes these most interesting huge rock pots. See: Dietmar's blog
They took a couple nice collected spruce in trade and were very happy and so am I. Now I can play with these. Some might be available for trade and sale. They are heavy, but I can just about carry most of them somehow alone.
