This is the second attempt at one of these, first one got cancelled for “poor presale tickets.” Truthfully, the organizers never got the local beer distributors on board and nobody would promote it for fear of pissing them off.
Second time around looks to be going much better, lots of promotion and local support. Between this and several up and coming local breweries, DFW is starting to get with the program.
