Well up in Seattle they outlawed a lot of plastic this and that's, water bottles etc. THEN they made a change at one of the big parks, either Safeco Field where the Mariners play or Century Link Field where the Seahawks play. The change: NO CASH ACCEPTED. So....you buy a little plastic temporary debit card with cash to buy your hotdogs, what do you think most people will do with that when they are done? Brilliant!
