Sure they do -- there's plenty of homeless people in the suburbs these days, it's just a different interaction.
It's homeless people standing on the sides of freeway offramps and stripmall driveways, dying in front of them on the grassy lawn road medians. It's handing change to a homeless person in the stormwater road ditch while you wait at a red light.
You see very few homeless people on street or in trains, and zero tents, in NYC. Its kind of strange -- NYC has a larger homeless population than SF no matter how you slice it (total count, per capita, per square foot) but the issue seems way worse in the major California cities.
I have friends who visit Oakland from NYC and are amazed at the Mad Max quality of the Bay Area.
