I think that Al has misundertood the question.  Parking Lot 3 is traditionally considered inside the circle.  Whether or not it is within 50 miles of the borders of the City of Saint Louis is debatable, but since the point of origin in question is in the middle of the river, it is also difficult to determine exactly.  Parking Lot 3 is nowhere near the north end of Carlyle Lake, however, which is many miles to the northeast.  It is the area north and east of Parking Lot 3 and Tamalco including Whitetail Access and Parking Lot 2 among other good birding areas that is in question.
