Attention Cadets: Can you keep a secret? Good. The Polka Police are busting the Adventureland Oktoberfest on Saturday, October 6, 2018 from 1-5 pm. Leave your kids at home because Saturday is the only day of the year that they are not allowed into Adventureland – 21 and older only! You do the math BEER + RIDES = ???. Lots of fun and music including Hanson.
