Permission is better...

Here's the proof. Comments from finders on one of my boxes:

"The gal behind the counter was thrilled to see "a letterboxer doing his thing...never seen one before, actually doing it..." I guess that's opposite of seeing a letterboxer not doing his thing and not realizing he's a letterboxer because you never even knew people like that existed in the first place :)"

"It was fun going into the gift shop and chatting with the two ladies at the counter. They are both quite into the whole boxing thing for not being boxers themselves!"

"Loved the location. Met the director and staff. Had a wonderful time!"

Well, that speaks for itself!
