It used to be true, when CA required a 6-year degree to be licensed and only really CA schools were offering that degree (everyone else had 5-year degrees). But it's been over a decade since this was the case.
If you're worried about networking in CA, you could always try to arrange a rotation in CA from your school in a different state. Alternately, there are some organizations with annual meetings in CA (well, at least one) that you could attend while in school to network.
