Pit Stop 03 - A muggles paradise.
No seriously, it took me 4 attempts to place this cache. This location is busy all hours of the day and someone is always parked next to GZ. Hopefully you have better luck finding it than I had hiding it, go during non-rush hours to increase your chances of scoring the spot next to GZ. Have fun!
Congratulations to polecat42 for being FTF!
