Sandra Faber is University Professor of Astronomy at the University of California, Santa Cruz.
Neighboring Lancaster has increased its population since the early 1980s to around 3 times its former level. Major retail has followed the population influx, centered around Palmdale's Antelope Valley Mall. The Antelope Valley is home to over 475,000, and is expected to reach 1,000,000 people by the year 2020.
Just looking at the map doesn't account for all of the traffic. I would live in the newer part of Natomas or maybe even Elverta if I had to work in Yuba City. Antelope is a smaller suburb of Roseville. It's OK too, but not nearly as nice as Rocklin or Folsom.
