A strange new anthology considers whatever became of the characters from Born to Run
's "Meeting Across the River."
The link goes to MetaFilter, but from there there are links to some reviews.
Apparently some Springsteenologists consider "Jungleland" a continuation of "Meeting Across the River." I've never thought that, but I've always been certain that the Mary from "Mary's Place" is the same person from "Thunder Road," just much older.
