Also you want to be careful about leaving stuff in the trailer because they may become part of that trailer forever. This happened to my favorite travel pillow. Someday I may find it again if I get that same trailer, but I'm not holding my breath.
At times I've found random books left behind, copies of the LOST magazine, fan mail, etc.
But this day I found more than I wanted. They've warned us not to leave things in the fridge because the trailer gets turned off and driven to the studio or next location nightly.
Apparently someone was enjoying their spicy jack cheese and avocado plate so much they wanted to save it for later.
