Join our Rock Rewards Challenge for your chance to win a growler

Not sure how this is legal in all states where there are Rock Bottom locations…but this is a novel way to incentive repeat visit during the month. I am not sure if you have to show your Rock Rewards card and 4 “visits” are just checks, regardless of the items on the checks? What if the only items were beer, would this be an incentive promoting consumption of beer? So many questions.
