Good story. I would add make it tough on thieves. Since you can't guard your property 24/7, your last line of defense is a padlock. Use a lock that thieves can't use a bolt cutter on. Like an Abuslock diskus padlock. I would be willing to bet most if not all those storage units were secured with a cheap long shackled padlock that could be easily cut with bolt cutters.

Remember, you want to make it harder for thieves, not easier!
