My hubby and I travel a little bit, and we always hit a museum if it is anywhere near to where we are staying. Then we find a nice place to have lunch. It's a really relaxing thing to do, and you'd be surprised at what you just might learn there. Let's just say, that I'd rather do that than spend 2 hours on facebook.
I try to go as often as I can and see one in every city I visit. I actually went last weekend to a Surrealist exhibit that I hadn't been to in awhile. My bf and I enjoy going together. I also studied a bit of art in college and abroad.
