Note how the mouth of the Largemouth extends under the eye, while that of the Smallmouth stops short of it. A lot of fishermen seem to think everything they catch is a Largemouth.
My preferred launch point is on the river behind the little strip mall off Route 527 / Old Matawan Rd. I have never had a problem parking here, although I don't think this would be a good place for a large group to show up. Entry can be messy if the water is low. I wouldn't wear white. The launch site is pretty muddy at low tide, try to hit this spot when there is plenty of water.
