The Great American Beer Festival, slated for next month in Denver, sold out in one day this year. However, you can still win tickets to the festival through a contest sponsored by VISIT DENVER. One lucky winner will receive two tickets to the Great American Beer Festival on Oct. 11 to 13, as well as two nights' accommodation at the SpringHill Suites Denver Downtown. Winners will also receive two round-trip tickets on Frontier. As it revolves around beer, you must be 21 or older to enter the contest. The contest ends on Sunday at midnight MT.
