Have you ever had these thoughts?

Wishing you could go back in time to cherish what was? I think about The SD&AE all the time and wish I would have built a scrapbook, taken pictures or at least some notes. When I drove the mainline from 10th Ave. to Palm City a few weeks ago, nothing looks the same. I mean first theres the trolley development that overshadowed the mainline to begin with. I knew where some of the industries were, that are gone. Southern California looks like one big Costco, most of the history is gone. At least in some of the older areas of the country, they never change. I don't know what it is about Southern California that it had to change so much and it's history is in museums now.
