SW Nebraska? Anywhere near Kimball? We lived there when my dad worked on Minuteman missiles back in the 60s.
I was in Kimball..we camped at the lake..my father worked on the minutemen sites. We lived in Rapid City..Cottonwood, SD; Scottsbluff, Kimball to Cheyenne.
Cottonwood was a ghost town. There was a state farm across the highway..rode horses named Commanche and Flash..no saddle. There was a farm pond..the horses liked to swim. There was wooden diving board..I tried to get Commanche to walk on the board..so we could jump into the pond...the board broke and we crashed into the water..
I was in the 7th Grade.
Lost two rod and reels at the lake in Kimball..fish pulled em in..shot many ducks at Scottsbluff on the river.
