The McMansions are all occupied as far as I know. Most of them were built several years ago. The duplexes which were there were in fact ugly even in the 1960s. They did allow those of lesser means the ability to go to Lakewood schools however. It's one of those 'be careful what you ask for' things..
The train tracks behind Santa Barbara are slated to be made a jogging trail. That train hasn't run for many years. There is a crop of McMansions on that street, too...

Glad to hear you are coming to Lakewood - lots of activities this time of year (I'm off to homecoming weekend in a few minutes), hope you can make some of them such as the home tour in a couple of weeks.
