One of the most dogged opponents of the Keystone XL pipeline is John Harter, a landowner near Colome in Tripp County. He fought in court to keep TransCanada from siting the pipeline across his land, and he lost. At the Public Utilities Commission hearing in Pierre, he is an intervener, and as such may ask questions of TransCanada’s witnesses. Although he has a quiet voice and slight stature, he holds his own in a room full of lawyers.
