A quick P & G; no room for swag or a pen. BYOP, and bring your stealth!
Since I've started this endeavor called Geocaching, I've been thinking that this would be a great spot for a cache.
Muggles can be present at any time of the day; some days more than most, espcially weekends. Be wary of any that might be out watching you from the "cage." It's usually best to come up from behind them as to not let them see you.
