This photo was taken at our pit at CMP. We had a rolling toolbox, rolling workbench (homemade of 2xs plywood and pegboard, lovingly painted), rolling shelves, robot cart, homemade rolling wooden battery box, the frame of a 10'x10' popup canopy, and some string lights. Simple but quick.
This year, we're planning a bit more of a themed pit. Veronica (yes, the same Veronica as inside the Oscar outfit) is going to make our pit look rather like a castle. The functional bits will be essentially the same, though we are planning to build or buy a new rolling workbench.
