 Because there was a gentle southerly slope of the land in town towards Daley Slough, by the time the sidewalk reached where True Valu hardware was, it was four feet off the ground and required steps.Daley Slough was a large wet area taking up more than the block where Longfellow Square apartments are today at 416 Sibley Avenue South.It was deep enough that some old-timers remembered swimming in it.
