In downtown Sheboygan, nearly 70 bands, dignitaries, veterans organizations and other groups will appear in the city's annual Memorial Day parade, which organizers said continues to grow after nearly being cancelled three years ago because of low participation. The program begins at 11:30 a.m. In addition, arrangements are being made by the Coast Guard Air Station in Traverse City Mich., to have an MH-65 Dolphin helicopter fly from Waukegan, Ill., over Deland Park about 12:30 p.m. during the Lao, Hmong and American Veterans Memorial ceremony.
