The big misunderstanding of Dives is their stupid, their not. The thing to keep in mind is, up where they're hatched it's so remote that they have very little if any contact with humans. They don't know to fear us, but they learn real fast. In a few weeks the St Lawrence will have tons of Old Squaws on it, making their way up North to breed. Their first week on the river, you will be able to drive your boat within a few yards of them before they take off. A few weeks after that and you won't be able to get within a few hundred yards of them before they take off. With experience comes education, even for Divers.
