This is on private property with the permission of those that control it. Please be courteous on Sundays and Wednesdays. If you see a group of younger boys watching you on those days, they're likely NOT muggles. The challenge of this cache could very well be logging it on a Sunday or Wednesday without being "caught" by a younger geocacher. You may see the parking lots used other days as the parking lot functions as overflow parking for a nearby high-school so you may have to be more careful of muggles then. You're looking for a small camouflaged container.
