Someone give Brother Randy an AMEN!
Well said. My wife and I crossed the country on a sightseeing trip in 2012, and there were several (some RR, some not) museums we encountered that we only open 3-4 hours a day and not at all on weekends. Even she started to ask, "How can they stay open at all, with hours like that?"
How, indeed? Many weren't open on weekends at all.
There was a big NASA-related museum near New Orleans that I was livid to find out wasn't open on Sundays. I doubt I'll ever be back that way by car ever again and that probably my only chance to ever see it.
I've also seen museum buttoned up when it was supposed to be normal working hours. We were at the pier for the USS Hornet in Alameda a few years back, on the right day of the week and time for the hours posted at the gate, but it was closed. I was livid then, too, as we crossed the bay just to go there and also won't likely be back that way...
