Sorry to hear the spa is closed; the general public does not go for that sort of thing anymore... Forwarned! The best info and interest of a trip is through the wonderful people met along the way...

I was talking to a geologist yesterday who mentioned Fantastic Caves. She calls it her 'Women's Lib' cave! Near the exit the members of the Women's Atheletic Club, who originally explored the cave, signed their names. (The farmer who owned the land- and the discovering dog- put an advertisement in the newspaper for someone to explore the caves for him; the women's club [perhaps the only respondants], got the job.

The jasper and moss agate, etc. is a better bet than the tiny yellow diamonds. Happy trailings!
