5/09/2005.  While looking for Rambling Creek Park, Ceferino Santana, dog Sonar and I discovered this linear park with its back to the woods of Rambling Creek Park.  The park is small, but attractive.  We looked for some trails that might take us into the woods of Rambling Creek Park, but we could not find any.  That seemed a shame.  (We would find out later that day that there don't seem to be any trails in Rambling Creek Park anyway.  It seems to me that they should try to create a greenway using Watson Park and  Rambling Creek Park, heading past the soccer fields on Chief William C. Forst Lane, the buildings of the Department of Parks and Recreation, and Carlton Field off Carlton Avenue.)    Dr. Patrick L. Cooney.
