Back in the stone age when phones were actually phones and you had to buy a dedicated GPS if you wanted positional information, I was in Washington, DC for a meeting. While there, I decided to find a geocache that someone had hidden just outside the fence near the White House. Yes. That White House! I was being very discreet and only peeking at my GPS occasionally while walking slowly to get bearings. Any time someone approached i put everything in my pocket so I would not be noticed. Very discreet indeed.
At one point, I pulled out the GPS for a peek and while distracted, someone snuck up behind me unnoticed. Some big guy murmured into my ear: “I know what you’re doing. Just keep going. You’re heading in the right direction.”
I quietly said “Thank you.” and found it.
So bad place to loiter? In front of the White house.
