The Baltimore Beer Week Passport

No, as far as I know, they won't be checking you at the door or the border for it.

This year, Baltimore Beer Week (BBW) is debuting a limited edition Beer Passport- a comprehensive guide to all beer-centric venues participating in BBW 2010. The Official Baltimore Beer Week Passport is designed as a keepsake; it will help you geographically locate BBW venues throughout the State of Maryland and provide vital contact information for these participating establishments. The interior pages can be used for note taking, autographs from your favorite beer celebrities, and more…
…so get you Beer Week Passport and use it to chronicle your journey while "Celebrating all Things Beer in the Land of Pleasant Living"!
There will be only 1500 BBW Passports produced this year. All attendees of the Baltimore Beer Week Opening Tap Celebration will receive a Passport at the event. Additional Passports will be sold at select events throughout Baltimore Beer Week for a nominal price of $2.75 (Yes, Two Dollars and Seventy Five Cents!), wherever Baltimore Beer Week schwag is sold.
