Not archaeology, just the occasional pleasure of looking around fancy neighborhoods. I read this article about Ann-Margret putting out a rock album at age 81 (more power to her!) and they mention that she has lived in the same home since 1968 in Benedict Canyon in LA. Start looking around - it's in a nice area on several acres but in fact a 5,400sf house in Beverly Hills terms is modest. Four bedrooms, four baths. There's a pool, but not a lot of parking. That may refer to garaged parking. Also, the surrounding buildings probably aren't included in that number. It was built in 1938 and has History - Bacall and Bogart lived in that house when then were first married, and then Hedy Lamarr lived there, apparently who Ms. Olsson bought it from. A blurb on a Hollywood website says

This lovely home, lavishly expanded to enlarge the living room, atop a lower floor entertainment, has been owned by Ann-Margret and her late husband Roger Smith, since their marriage in 1967. Previously, it was the home of Hedy Lamarr, who purchased the home from Lauren Bacall and Humphrey Bogart.
The Smiths added a private gym, a two-bedroom home for their live-in cook and chauffeur, a 20-seat screening room, and two guest houses.

Anyway, sometimes I read a story about someone who has stayed in the same place for a long time and I wonder how they've made it their own and what about the area makes it right for them - not keeping up with the Joneses and buying new bigger places over time.
