Fire On Oak Fest promises a hot time Saturday in downtown Baraboo. The third annual event benefiting the Baraboo Fire Department will return to the street outside Brothers On Oak, the fundraiser’s sponsor. “Every year has gotten bigger and better,” said Brothers On Oak owner Grant Slayton. Firefighters will sell brats, beer and raffle tickets to raise money during the block party, set for 1-10 p.m. A disc jockey will provide music until the popular regional band Madison County starts playing around 6 p.m. “The whole area is crazy about them,” Slayton said.
