Tom Rice, grandson of Lloyd Stover (one of surveyors who named Stover Bay) and long time Long Lake summer resident has found a way to share his hobby for collecting brochures, maps etc from Long Lake's past. He has started a blog. As Tom says:
It's a "very, very skeleton first attempt at a blog.... I picked the Park Rapids theme to show off a few of the early northern Minnesota lake brochures I’ve collected over the years."
