Public Storage Unit
How wealthy do you have to be to consider a wing of the local art museum as your very own public storage unit? Turns out that some people store their huge collection of classic and modern art in these wings since it was more practical than private storage. Ah, to be rich.
Sure, this might have a nice practical upside for the family and the public but for whatever reason though, the amount of wealth represented by this arrangement seems truly staggering.
