We are driving from Yosemite Valley to San Francisco airport to catch a 6pm flight to LV in October. Hubby is obsessed with the film American Graffiti and so wants to stop in Modesto on the way. I can't seem to find any info indicating there is much to see to connect Modesto to the film these days. Is this correct? Is it worth stopping to indulge my husband's love or will he just be disappointed?
