Bring your Hackerspace Passport to the Milwaukee Makerspace and we’ll stamp it for you! And once you’ve got our stamp head west to Sector67 in Madison and get stamped there… and then down to PumpingStation: One in Chicago and get stamped there. You’ll have a full book in no time!
(Note: If you don’t feel like making your own, Bucketworks printed up a whole bunch, and you can get one from them for $3.00, which covers the printing costs. Oh, and if you stop by Bucketworks, get them to stamp it too!)
