The free-admission-Tuesday phenomenon at Balboa Park museums was one of the first San Diego freebies I learned about here.
And now, I've finally lived in the city long enough to actually want to take advantage of it.
Which museums are involved rotates, and the free-ness is for San Diego County residents and active military and their dependents.
Today is the fourth Tuesday of the month, which means you can wander San Diego's Air and Space Museum, Automotive Museum, Hall of Champions or the House of Pacific Relations International Cottages.
Special exhibits, like "the science of...aliens" at the Air and Space Museum may not be free.
Fifth Tuesdays are not free, although there are some Balboa Park institutions that always offer free admission according to Balboapark.org's schedule.
Air and Space final entry is at 4 p.m. It closes at 4:30 p.m.
Automotive Museum final entry is at 3:45 p.m. It closes at 4 p.m.
Hall of Champions closes at 4:30 p.m.
Cottages close at 3 p.m.
Between $8 and $24.75 for an adult.
The reason it took me several weeks to want to hit up free-museum-day is because on the East Coast, indoor activities are reserved for days that are rainy, freezing, unbearably humid or otherwise uncomfortable - which is much of the time.
It is, of course always free to stroll around Balboa Park enjoying San Diego's amazingly consistent good weather. You can even park your car for free!
