I was wondering the same, but I don't think it's a date (other than the 2017 mark). I've seen 0401, 0402, 0403. Plus, there is no way KD has been sitting since early April haha. It sucks that quite a few people are taking advantage of the system, but I think it isn't gonna change. I'll take my allotment (often, with less than the full amount) and laugh at those spending $300+ on cases of beer. To those who attended...any word on if Key Bump will be paired with another beer?
