The container is a small, devious one that might initially escape attention. Micro log file that requires a special extraction tool is required. If you have trouble pulling the log then I'll take your word for it that you found it :) Take care in parking, since there are indeed nearby lots in various states of surface disrepair. I would avoid this area after dark and keep your urban exploration devoted to daytime.
Try to use some geosense as you approach GZ. That should help guide you toward the prize. And please return the container exactly as you found it. There might not be a ton of muggles about, but passersby and businesses still open nearby could be something to consider!
