The next best thing to keeping picks is being able to make new ones from found objects...esp. (expired) credit cards,or milk jugs..with this handy tool...like an overgrown paper punch,http://www.pickpunch.com/
If you get promotional credit cards in the mail, these are prime targets
(i sometimes keep one of these cards in the glove box to use as an ice
scraper for the windshield...) but the pick punch creates new cards. it come with a sanding block to smoothe the edges. they work great in a pinch, and the embossed numbers and letters help you to grip them.
