Thanks for the link. great story. Lets keep the spread of the zebra mussels to a small as posible area on the island. Its there and once they take over it causes major changes. Just look at what it did to the underwater sunken shipwreck diving areas in lake huron to see how distructive this little pest can be. Richard
