Come and see the wacky costumes judged at 11:45 a.m. and witness the plunge into Clearlake at noon.
Those too chicken to take the plunge may join the chicken coop and stay dry. A post plunge party hosted by the Kelseyville Lions will follow the plunge.
This is the group's main fundraiser for the year, which supports more than 100 developmentally delayed athletes as they participate for free in basketball, track and field, golf, weight lifting and bowling.
