I would encourage you, and everyone else, to look up the GPS coordinates on the googles before trying to say you are approaching the base. Getting there is more of an encounter as a team as well, but can be done alone if you choose.[/quote]So I Googled Hall of Justice the JLA Base in Metropolis.

I am not seeing where it would take a team to get there. Any one can walk up to it. Looks like a walk in the park, literally.

As for GPS all search results come up with real world locations.
