An idea - try posting this question on the Fred Miranda site (fredmiranda.com), if you haven't done so already. Not sure which forum is best, but try the landscape forum. There may be more people at Fred Miranda familiar with the Fresno area (film-wise), since it is a gateway to the western Sierra.
Where else are you planning to photograph? There are a number of people here who are familiar with the Sierras, Yosemite, Owens Valley, Death Valley, Big Sur (on the coast), etc. Also if you 'search' here on those keywords, you'll find a number of old message threads on these topics.
