In Oklahoma, when the Maxim magazine came out, I printed up shit tons of YFTC and went around Lawton trying to find places that sold Maxim. I scoured that town and put cards EVERYWHERE.
Then, when I'd come back and find that Maxim wasn't really selling, I'd buy several mags and leave them at various Starbucks, open to the Scientology article, with a card placed at the end.
