5. 20 Exchange was a Serious Urban Exploration Destination
We had permission, but don’t do this on your own.
We got to the roof just by asking. But urban explorers have come from around the world to try and get to the top. If you’re thinking about trying it now though, you might want to think twice. Building management was clear that they’ve figured out all the tricks – catching (and arresting) five people who came on the roof just a week before we visited.
