So I recently took a trip to the Metropolitan Museum of Art, and let me tell ya, it was pretty great. All kinds of beautiful art, and fancy furniture, that would all look great in the basement I currently live in. And I am proud to say that I paid a quarter to get in. I don't feel too bad about that, since the entirety of the museum is taken cared of by the Rockefeller Foundation.
If you've never been to the MET I say you should give it a shot. I'm more of a MOMA guy myself, but the MET was an insane collection of beautiful art of all varieties. It's fun, educational, and fucking gigantic. It's amazing how much stuff they have on location!
Just do yourself a favor and pack a lunch; the cafeteria is overpriced.
