I took a helicopter ride from Vegas that landed *in* the Grand Canyon :D
I lived in San Francisco for 9.5 years before I went to the Modern Art Museum which is kind of lazy of me because I love modern art &amp; whenever I visit somewhere I always put the modern art museum on top of my list. I had a stay at home vacation last Fall and did a lot of the SF things I should have done many years earlier - visit the main library, the City Hall, etc. The one thing I have left to visit is the Academy of Sciences. It's only been open a few years and I tried once but the line was ridiculous so I have an excuse.
