Thanks for your comments, I appreciate them..

I enjoy asking myself difficult questions, however difficult the answers.

I think my initial thought was that do people go to museums these days because they're on the 'tourist' route. Or because they like art. And not just the Mona Lisa.

Secondly, there is no other better place to hang art than a museum. It needs to be safe and accessible for people to see. But it sometimes looks out of place. Bristol, where I'm from, still has numerous Banskys on public walls. Parts of the city have now become a museum in itself.
