You'd have to be nearing your 80th birthday to have witnessed or been conscious of war-related activities in San Mateo County during World War II.
If you're not that old yet, or would like to revisit those years, a retrospective opens Wednesday, Dec. 7, at the county's History Museum in Redwood City. The date is significant: it's the 75th anniversary of the attack on Pearl Harbor by forces of the empire of Japan.
"Although armed attack never touched San Mateo County, the importance of the Peninsula in terms of wartime preparation, training, industry and logistical support was immense," says Sarah Phelps of the San Mateo County Historical Association in announcing the exhibit.
The exhibit will include presentations on the detention of Japanese-Americans in camps in San Bruno and in Pacifica, artifacts from soldiers and airmen and from local civil-defense efforts, photos and maps of coastal defense installations, wartime modifications at the San Francisco airport, newspaper accounts and radio programs including "fireside chats" from the president.
The museum is open every day except Monday from 10 a.m. to 4 p.m. and is located in Redwood City at 2200 Broadway, inside the Old Courthouse building.

Admission is $6 for adults, $4 for seniors and students, and free for children aged five and under.
