Your best bet would be to contact a club in that area and ask them your question. They would be the best bet to get an answer.

You can find AMA chartered clubs by using the AMA Club locator

Another way might be to search the RCU member list for people in the San Diego area.

This is the RCU member list search function. Once there you can select to search by city and then enter San Diego in the keywords box. This will give you a list of RCU members in the San Diego area.

One final option might be to contact hobby shops in the San Diego area. Here is a listing of Hobby Shops in the area as listed in the Yahoo Yellow Pages.
