Make sure all your pack pockets are open when it is left out for the night. I've left this and that in those pockets over the years and the worst that has happened is there are a few ziplocks that have been chewed through.
If you leave anything out at Trail Camp for any length of time, it will disappear. I lost a gallon ziplock with all my breakfast food the only time I camped at TC.
If there's no food in backpack can I leave my backpack inside tent with me? You said they just take gear, makes me not want to leave any thing outside. Makes my blood boil....
