04/05/2005.  I did not know if there was a trail here or not.  So I just starting walking along the park's boundaries.  In the far right corner there is the start of a trail.  There is a combination set of stairs descending the small hill and a bridge over the stream.  I figure from the appearance of the setting the trail is a circular one around the central hill here.  So I decide to go counter-clockwise, turning right. The stream soon flows into a bigger one and the waters head under the Gilbride Road Bridge.  The buttercup Lesser Celandine was in bloom.  It is an invasive species but with its bright yellow, glistening petals it sure is attractive.  The trail heads uphill with the stream down below.  I keep turning left and find myself back at the bridge.  Dr. Patrick L.
