Feb 13, 2013 — Winter has been a cooperative partner for Ottawa's winter carnival. Plenty of snow, ice, and temperatures mostly below freezing have kept the main events in fine form. This weekend is the last weekend to enjoy Winterlude in Canada's capital. The Rideau skating canal is a huge crowd pleaser. But so are more than a dozen ice slides carved into huge mountains of snow in Jacques Cartier park. There are kiddie slides and long, wide chutes that half a dozen people can slide down together. Two years ago, David Sommerstein and friends brought along a gaggle of kids. He sampled the slides, the sounds, and the crowds.
