I think of this as the sister site to the Orange Empire Railway Museum. It's one of the things that has made Campo an abstract treasure for me, along with the Motor Transport Museum, Freddy's Truck Farm, and Rick's Ranch.
The PSMRA, as they call themselves, is run entirely by volunteers, and has an informative website. Unfortunately, they're only open on the weekend.
I came here over a year ago, after spending most of the day at the Motor Transport Museum. I was tired, though, and didn't get out of it what I should have. So I returned on a beautiful day in February 2016, armed with my macro lens and fresh eyes.
A few of the abstracts are below. To see all of them, take a look at the Theme Portfolio.
