Coverage run in the West. I have now run within 100m of every point of land within 4km of my home. 50 km^2. And counting... Though the radial coverage extension is now blocked by 12 ft high walls, and barbed wire, at Lockheed's King of Prussia facility...
Coverage run in the south. Got started just in time as it began sleeting 5 minutes after I'd started, which would've been really tough to start in. Wasn't really dressed well enough for sleet, but fortunately the wind dropped just a big and the sleet lessened to rain, which was much more tolerable for this long run.
Explored a lot of streets in Stratford through Berwyn, going through the Devon train station tunnel twice, Mercedes Benz, Waterloo Gardens (closed down), and the bowling alley before discovering some open space off the south end of Heatherwood - and then running around the fairly well fenced, and very large property at
http://goo.gl/maps/K92sM - I'd guess ~$10-20M for that property - given the $2M 'little' houses those apparently sold off the edge of their lot as part of a development... That's going to be a serious coverage area challenge - esp. given the rather high fencing on all but the West sides of the property to complement the signage.
Next nearest areas to cover (run within 100m of...):
4.0km: E, Lockheed Martin, KoP - High fenced private facility - slender line in center more than 100m from all walls and fences [very difficult]

4.1km W, forested large yards on Mt. Misery btwn. Country Club & Horseshoe
4.1km, SW, neighborhood in N. Paoli, btwn. 202 & power-lines
4.2km: S, Berwyn near Rt. 30 & Leopard
