Heard a few Sandhill cranes go over head at 6:45 am. At 3pm, saw 67 go over. About 5 minutes later, another group of about 50 went over, then at 3:10 pm had a continuous stream of about 400+ fly over .... never saw so many before at one time; impossible to try to count after the first 75. All were flying due south lateral to 31E, just north of Glasgow. Linda Craiger / Glasgow
