In Minneapolis on Sunday, June 29, 1958, Dale wrote, “High 95°. Took Dalene and Diana swimming at Twin Lakes. Stan came home at 6:45 p.m. from a week-end at a lake.” Diana was a neighbor friend. I think ‘Twin Lakes’ meant Moore Lake Park in Fridley, about 3¼ miles north of home. The park had a beach with a swimming area roped off, seen below.
