The deYoung museum was built in 1895, and has seen millions and millions of visitors since its first year. And now, you can be one of the millions - for free! Every first Tuesday of the month, the deYoung museum is free from when it opens at 9:30 in the morning to when it closes at 17:15. Go check out their vast international art collections and special exhibits. And then you can say you did something cultural and educational when you were in San Francisco. Bucket list - check.
