I knew next to nothing about this small Inland Empire town, but there's a very good backgrounder on Pomona's history here thanks to MetroPonoma.com (although "Metro Ponoma" might be pushing it a bit).

There are a few more-or-less preserved architectural keepsakes in the town center, but fewer than one would hope. The Masonic Temple (1909) is in a style that might be called "bumpkin Beaux-Arts," but the building is still in use by the local Masons, bless their compass-and-angle-wielding hearts:
Just nextdoor is a handsome storefront building, the Rockroth (1910). It's no major architectural statement, but it's nicely maintained and has a lovely street-feel that made me want to set up shop then and there . . . perhaps selling nostalgia?
The Craftsman-esque Seventh Day Adventist Church a couple of blocks away is a bit the worse for wear, but seems to be have great potential for restoration. It flanks a lovely winding block of Gordon Street planted with glorious cottonwoods in full bloom.
