I did move enough junk so the driver's seat could roll back - so that wasn't it.
Most of a gilded, carved wooden Chinese restaurant dragon,
A mattress (on its way to be given to a theater for stock),
A Coke TM can (set dressing, not mess, I swear),
A museum flier for a Bernini show,
A red-white-n-blue painted drop cloth,
One (only one) English walnut - underfoot,
A sweater (it's Spring, the weather's variable),
A car jack and tire inflator gadget (flats happen),
A box of picture frames, tools, and straw beach mats.
That's a random and representative sample of the kind of crud this set designer at least carries around most of the time.
