Those events are in Cali cause they pay to have them there. The 3 Cali Tier II's always do well. In fact, I'm pretty sure San Diego will be a Tier I next year. The attendance at last year's championships was a result of dreadful marketing. The last Cali tournament is in July, the champs are in November. Over-exposure isn't the issue. The WTA did virtually nothing besides cursory advertising last year. Even expanding the champs to 16 players was a sign they thought the product would sell itself. Didn't happen. (Tickets to Serena's matches sold well, but one player does not a tournament make.)
California has an economy bigger than all but six of the COUNTRIES in the world. They certainly can support five tournaments. Attendance was good at four of them.

Not blind. Not uninformed. We are party to atrocities. But the response of the world after 9/11 is worth noting. Even our most dire enemies offered aid. We should all be so lucky.
