1:30Ann Frisch joined her daughter and granddaughter (who are not pictured) and about 300 others for a rally and march against the Alberta Clipper oil pipeline on Thursday in St. Paul. After the rally, activists packed a Minnesota Public Utilities Commission hearing in St. Paul. The hearing was the last of six in the public review of Canadian energy firm Enbridge's proposal to expand the pipeline, which carries crude oil from the Alberta tar sands across much of northern Minnesota to Superior, Wis. Five previous hearings were held in cities along the route from Hallock to Duluth. If approved, the pipeline could double its capacity to 800,000 barrels a day.
