Here in Southern California (Orange County) I have a long-established Goodwill Industries store about a mile from where I live. Plenty of business and inventory. Never bought a bike there; seen an old Puch, an old Murray, some X-mart stuff, but not too many bikes
But I might check this place out in Glendora - lotta old road bikes.
