If we're talking typical art museum, you probably walked around an expansive but sterile space, looked at some pretty paintings from a respectful distance, then went to the gift shop to buy a magnet of one of those paintings for your fridge. Okay, I may be personalizing that last part a bit, but you get what I'm saying. On the whole, a day at an art museum can be lovely, but it's often not terribly memorable.
Perhaps that's one reason why museum attendance has been steadily declining across the United States since the early 2000s, especially among the younger demographic. Another might be that, since technology satisfies most of our entertainment whims in the comfort of our homes, it takes something truly extraordinary to motivate us to leave them.
