This cache has been hidden in a place where I go often.... (almost every day)
You may see pictures of a Captain around the place. Don't worry... he's just watching over his domain. I can remember him from when all of us high school kids used to come up here for a cold drink or a bite to eat. We also used to hang out in the back parking lot because he said that it was safer for us to be there than to ride around town. He's no longer with us, but you will see his name all around the property.
The cache is not placed on the premisis, but it is within 50 ft. There is plenty of parking around here, and plenty of people wandering around, so the muggles probably won't pay you any mind while you search. Some of them know about the cache and they may watch to see if you can find it. More than likely...... you'll see me watching. Don't let the crowd worry you... they're everywhere, but they aren't paying much mind as to what you are up to. The difficulty rating is only because of the customers. 
Good luck!
