The last time I visited San Francisco, I was 12 years old and we were on a family vacation. My dad really wanted to tour Alcatraz because he was a huge history nerd. But no one else was really interested in going (it's haunted!) and San Fran was just a quick two day stop on our way to Disneyland. So he said "eh, next time, I'll go next time." There was no next time.. he was gone just 5 years later and never went back for his tour. You never know what life may or may not bring you. Enjoy the time you have.
