The YMCA summer camp will hold a cardboard boat race at 1 p.m. Wednesday, Aug. 6, at Hodag Park.  The kids will be split into four groups that will each pick a theme. A counselor will represent each group. Without the counselors’ help, each group of kids will build a boat out of cardboard and duct tape that their counselor will have to race against the others.  For more information, call 715-362-9622.
