Monster Mash Bash

There’s a frightening amount of things to do at this year’s Bash! We want you in your Halloween costume, join the fun inside the Oswego High School Field House! Get your face painted to match your costume, jump in the bounce houses, or win a prize in a tricky game. It’s an Oswego party that’s over 35 years old because it’s fun for everyone every year! Admission is $5 at the door and adults are free!
