Team_Tyto: In such a conspicuous place, the stealthiest way to place this cache is while wearing invisibility clothing which is most effective on a weekday during the day. Unfortunately, at such a time, I'm too busy doing actual work to pretend to be working. Congratulations to those who solved the easy yet not so obvious puzzle. It's a shame to archive this one without a single find, but I might revive the concept in the future in a more secluded spot.
