Friend of mine shipped a fresh deer hide to someone who wanted to make something with it via the post office. The guy got a notice to pick up the package at the post office,went in and the whole PO smelled like a dead carcass. The postman said they hadn't found where the smell was coming from,but when they did someone had hell to pay. The guy got his butt out ASAP.
Another trick. If the bank turns you down for a loan store fish in a safe deposit box.
