Ah, very interesting! Here in sunny Northern California, we rarely have this
opportunity to explore sub-freezing temperatures. Perhaps up in Tahoe, but
not down here in the lowlands. And speaking of lowlands, did you know, Dirk,
that our Sacramento delta near here was pioneered by Dutch settlers
disappointed by the Gold Rush that brought over their dike-making
technologies in the 1880's and turned the inland delta area into a virtual
Holland building dikes around man-made islands and draining them for some of
the best and most fertile agricultural lands in the state? True.
