This is interesting, but is there some way to say what the name of each prison is and where it is? Some of them look "nicer" than others, some are quite interesting-looking and I'm curious to learn more about them.

Yes, some identifier would be nice so that it would be possible to look up the info in for example the "Correctional Facility Locator 2010".

For example this facility looks interesting (looks more like some farm):

Wow, it does! It looks like some kinda weird Tatoonine farm-inspired thing.

Interesting that a lot of them seem not to have 90 degree angles for their walls. More difficult to escape or break in?
