Of course, southern NJ is a different matter altogether - my one
memory of Camden, collected while driving between Philadelphia and
Atlantic City, is not very pleasant. Mmm, actually, not sure whether
it was Camden or Cherry Hill (it was 13 years ago), but the drive
through whichever city it was was horrible; the place stunk. One would
hope that they've cleaned things up by now...


You were probably in Camden. What you likely smelled was the result of
industrial pollution that has to this day not been adequately cleaned
up. Of course if you were driving by Campbell Soup, no comment.
