The Sheboygan Jaycees is civic organization that has been running Brat Days since 1953. It is one of our largest annual projects with event proceeds benefiting local charities. Brat Days is run entirely by volunteers. Brat Days has something fun for people of all ages! Pumping tunes, entertainers, wild rides, contests, and so much more. Come down to Brat Days this year to see what it's all about!
