A post office called Plain was established in 1913, and remained in operation until 1936.[2][3]
Attractions and events
The town is the location of Plain Valley Ski Trails, a 25-km network of cross-country skiing and snowshoeing trails. A racing team, Plain Valley Nordic Team, is also based in the area.[4]
Plain serves the start and finish for the Plain Endurance Runs, a pair of 100-mile/100-km ultramarathon races that began in 1997. The races are particularly challenging due to the fact that neither pacers, course markings nor aid stations are allowed per the race rules.[5] This resulted in only four total finishers of the 100-mile race during the first eight years of its existence.[6]
