Yea - I thought the same thing about boats entering from outa state. Having some type of inspection at main entries to the state would help prevent intrusion.

Lake - your right on about the dogs. City of Stockton wanted to show how pro-active they are in preventing mussels. Maybe their using the same dogs that were trained to sniff out mussels, sniff out drugs as well. You know how every city is trying to save money right. That explains why Stockton has such a large drug problem. :+
