<p>Tar??? I was living in West Philadelphia 25 years ago – I was there 1983-1992 – and working in Center City all that time, and all the time since. I have absolutely no idea what rodney is talking about. I’ve never heard anyone complain about tar smells, unless maybe someone was resurfacing the road in front of their house. (And, believe me, that does NOT happen often enough to complain about. The problem is more the opposite.)</p>
