If you have a car built like a tin can, try this. I had GOBS of magnetic poetry, and a beat up Volvo. The trunk, er, boot was shelfy enough to protect all the little magnets as I drove, and enough room for people to make wordy playgounds.

When I would get out of work, I would always have new passages and pieces sprawled across the back end, which I kept a record of in my notebook. Just another way of proving people make excellent pets.
