Well, with high gas prices some Americans are reconsidering where to live.
Balancing the transportation-residence location question will be a major consideration for workers and families in the 21st century. So far Americans are thinking only cars, but that is/will change to living close to mass transit.
In England, Philip Badman told me both he lives closer to the central city, so has less train fare to pay, but has a higher mortgage. His daughter is planning to move further out, but she'll have greater train fare costs. Rethinking the trade-off is interesting. What are you thinking about the location of your current/future residence vis a vis transportation?
