Roadside history

Like a chump I can't help reading every historic marker and roadside plaque that comes my way. I appreciate reading about historically important places and events, but sometimes it's funny to see a commemorative plaque set up a considerable distance from the actual site. I know of a marker on Monterey Road in South San Jose pointing out the New Almaden Quicksilver Mine...12 miles to the east!

This one in Compton isn't quite so far off...sure it's on a semi-major street, but with no street parking allowed and only private parking lots nearby, it's not very accessible....
