I find Tom's notes of flight direction to be pretty intriguing. It's always fascinating to take part in observing these morning flights, but it can be even more interesting to see how the flight direction varies over different sites.
This reverse S-to-N flight is obviously most famous along the west shore of Cape May, but seems to be regular in smaller locales also - like Tom noted in CP. On my patches in Bristol County, Rhode Island, I watch flights going S to N on any morning of suitable winds ...presumably due to birds reversing up the peninsula instead of making the jump across the bay. >From the records of many diligent observers, the fall flights along the south >facing shores of the LI barrier beaches and the Great South Bay are >consistently E to W.

These flights never cease to amaze me in their dynamic nature and in how they vary based on location. It seems their direction is a function of more variables than may meet the eye (geography, weather, shorelines, etc) and I'm sure a lot can be learned from comparing them over various locations.
