		March 6th, 1886 Stanley lit the downtown and rejoiced along with the townspeople. The system lit both businesses and the street with 150, 50, and 16 candlepower incandescent lamps. Stanley remarked how people were happy however maintained some distance from the lights as they were afraid of them! They had growing pains but it was a grid system.
