This is a pretty interesting location for a street sign so I thought it could use a cache. There are two ways to approach GZ, so there are two different parking locations, and each of them is close to the search area. There is also a white line painted on the concrete that you should not go across. If you are lucky enough to see one of the Metro railcars go by while you are here you will understand what I mean. There is a high possiblity of dog walkers in the area so please be stealthy and replace as found.
