Whitebreast Point, Lake Red Rock
In northern Marion Co. From the south end of the dam, follow T-15 three miles, first south and then curving west, to S-71. Take S-71 north (right) about three miles to the Whitebreast Point area. Turn left just before S-71 goes downhill to the water (which is itself a viewing point), and scope from--among other places--the boat ramp area off left, and Whitebreast Point itself at the end of the road, about one mile.
