Why do SF Bay investors skip Fairfield/Vacaville for Sacramento?

[Bill Fried]

I've been looking around the Sac/Folsom area for singles, duplexes, and quads recently and this time on our way back home to the Bay Area we stopped in Vacaville and Fairfield and found they were both very cute and reasonably priced. What am I missing? Is this not a decent place to invest in real estate that's half as far away as Sac/Folsom?

Thanks.
