The Things We Carry
For trial, I have a collapsible wheeled file box (like one of these, but I have a cheap generic one from OfficeMaxDepot). When I'm not in trial mode, the box folds up and stores under the couch in my office. When I am in trial mode, the box expands to about 13.5″W X 12.5″L X 13″D - big enough to hold several large 3-ring binders, my code book, my laptop and its charger brick, a couple of low-carb meal replacement bars, and a plastic box for small supplies.
In the smaller box you'll generally find:
Exhibit stickers.
Highlighters.
Markers.
Pens.
DVI to VGA converter (for hooking my MacBook Pro to the courtroom display).
Listerine breath strips.
Verizon Wireless Broadband adaptor.
Hand wipes.
Post-it notes.
What do you carry with you to trial?
