While on my lunch break trying to hide another nearby cache. You'll be looking for a nano so BYOP. FTF gets bragging rights. You can attack GZ from two different directions. If you park near city hall, pay attention to the parking signs as some are for permit holders only. Muggles could be a problem here. If you're approaching GZ from the neighborhood side, you won't even have to enter into the park, but still beware of muggles.
