Some or another person has run an earth mover around smoothing things down, removing a mound of hardened asphalt and generally tidying up the place.
It's hardly a smooth place to run around flinging frisbies, but we're definitely getting somewhere!
Sad to say, some people still seem to regard it the place as a receptacle for take-out coffee cups, empty beer cans and discarded springwater bottles (why concern for personal purity inside... but not outside, in our environment?). On the upside, people also toss away relatively clean plastic bags, which are convenient for use should you care to pick up stray bits of candy wrappers and such as you saunter along. Good bending exercise... a distraction while you wait for the dog you're walking to inventory the aromas left behind by fellow canine strollers.
