Join Blackbird Cafe Monday and Tuesday, May 14th &15th, during Happy Hour (2-5pm) and enter the Boulder Mojo Nitro Mustache contest! All you have to do is show up, order a Mojo Nitro, give yourself a wicked “Beer-Stache” & have your polaroid taken by one of the highly trained polaroid photographers to enter. Voting will take place through Friday at Blackbird and the winner will take home a pretty sweet Boulder Beer Gift Basket.
