There are quite a few Citabrias available for training and rental locally, including my home base of Hawthorne, Torrance and Santa Paula at least that I know of. Santa Paula is well worth a visit especially on first Sundays when the hangars are all open.
You're welcome to a scoot round in my RV-8. Feel free to PM me.
If you haven't found it already,
Pacific Flyer often has some good local info.
