The trickiest spot is just above the Turnpike bridge. An island splits the river here. At the very bottom of the island in the left-hand channel lies Pam's Rock, a boat-length off the right shore of the island. Much of the water down this channel hits the rock and lasts off to the left, almost perpendicular to the river course. Run well to the left of Pam's Rock to avoid this cross current...it's a flipper for beginners.
