Are All Places Nostalgic?

Walking through the USC campus yesterday, I began to walk by landmarks that were especially nostalgic for me. A scaffolding tower on the football practice tower where Christy and I climbed to gaze at the downtown skyline, the swimming pool where I swam, the track outside of GFS hall, the Doheny library, etc. But in between these landmarks, I noticed other spots with which I had no personal connection, and I began to think about the nostalgia these places might hold for others. A window in a dorm, a table in the student union, etc. This led me to wonder whether or not ALL places have nostalgic potential, and how many places we all pass by daily without a thought, that might be laiden with nostalgia for others.

What makes a place nostalgic? For whom? What experiences are most salient for nostalgiac recall? How are these experiences conditioned by culture?
