Throwback beer cans — Got a church key?

Wrote reader George Berger, "It's something I've wanted ever since 'Mad Men' reminded me of them. Now if they'd just come to Phoenix."

Justin Hawkins and Adrian Grenier (who starred in HBO's "Entourage")  co-founded Churchkey Can Co., a craft brewing startup that brought back beer in flat-top steel cans. The cans require the use of a church key to open them, just like they did 50 years ago.
