Hey, I think your research is great I would be glad to help you out. Did you know that Kentucky is home to many endangered fresh water mussels. Also our state has one of the biggest freshwater mussel population. Ohh yea Kentucky's got it all when it comes to mussels. I know you are looking for whole pieces that are not broken. Would you like some from lakes creeks or the river? Do you have any sizes that are better than others? Just send me a message and we can set something up. I am going to the river tonight, don;t see why I can't pick you up some then.
