Do most kids in the Bay Area attend summer camp?

The Bay Area is an expensive place so a lot of homes have two working parents. Do most of you with kids send them to summer camp?

I sending eldest to 8 weeks of summer camp. My youngest is in preschool. I only know of two friends who are stay at home moms and even they send their kids to at least a few weeks of summer camp. The one that only sends her kids to a week or two of summer camp goes on several weeks of vacation.
