When you are invited
There was a time in my life when I was completely disheartened by the USPS because they wouldn't mail a rock for me. I decided the solution to this problem was simple: The Llama Express. I went as far as making uniforms, and job applications, but I never got around to getting the llamas. I thought this was my chance, but based on the appearance of the farm and this sign, I wasn't sure how much they would enjoy a random visitor. Especially, one who has make believe ideas about a postal service using llamas for delivery. One thumb down, because the place was very hard to find and I had to pay my first toll since Chicago, to use a bridge crossing part of the Chesapeake Bay.
