Carl; I used to live in Fresno. I believe it is on Manning Ave & Freeway 99. Fowler has it's own zip code and is just north of the location of the demised Casino, it is a Church now... Is that ironic? Selma is another couple miles south. Selma "the Raisin Capital of the World". Sun Maid etc. Also, I used to work for the Post Office in Fresno, and most Post Offices offer PO Boxes, that can be a reason.
Hope I helped
