Dear Charlie;- I do a volunteer job at the Museum here. I am checking and helping to identify over 4000 lots of fresh-water snails----TO BEGIN WITH! They all look green and brown and dirty. Say described a lot of them---which partially explains why he got out and went to Indiana. We do have some nice streams around here with FW mollusks. We also have some wonderful layers of Ordivician deposits showing the occasional trilobite and the more common brachiopods. I have to go about 40-50 miles to go "up" to silurian and devonian. Art
