I've learned the hard way to ensure the hinges a securely fastened. As I preflighted at home, before I left and found a loose hinge but decided to wait to get to the airfield first before I fixed it. To make it short I forgot to fix the hing and ended up spending a week trying to find my airplane in razor grass that was about 8 feet tall. Important do a preflight just before take is just as important as doing it before you leave for the airfield.
