I can't speak for JST because I don't bowl it, but there is no way JAT will ever get further south than Irvine. Even when it's in Orange people complain. You have to realize that 1/3 of JAT is from Ventura... San Diego would be almost 200 miles for them. I live south of everyone and it sucks, but that's just the way it works.
