Six people joined Adrienne and I for a pleasant morning of birding
the south 
end of Oaks Bottom Wildlife Refuge this morning. We began at the
upper, 
southern parking lot (near the baseball diamonds), walked down the
hill, then 
over to the amusement park and a river view. Retracing our steps, we
then 
walked north along the east side of the lake.
