Annette Choszczyk lives in rural western Colorado these days, but when she was a kid, the Highline Canal in Denver was her summer paradise.
“To us, it was river and a playground, complete with rope swings, swimming holes, crawdads and a trail alongside it that adults and kids could walk on to the foothills or far out into the prairie.” They always called it a ditch, this 71-mile-long canal that carried water all over Denver.
