Here’s an item from the Ontario (Calif.) Daily Bulletin that’s a bit discouraging:
RANCHO CUCAMONGA – The historic gas station on Foothill Boulevard west of Archibald Avenue, one of the last relics of the Route 66 days, has been fenced off for some time now but the city says no plans for the station have been set in concrete.The station dates back to 1915 and there were once talks of constructing an office project that would incorporate the landmark, but the approval for those plans has since expired. The city says without developer involvement, the station’s future is uncertain.
