Only a particularly crass sort of person — that would be us — could find humor in the knowledge that the city of Dallas will spend $2 million to partially remove the Standing Wave, the pile of concrete that the same people who supported the Trinity toll road decided to toss into the Trinity River to create fake rapids for the entertainment of kayakers. Built for $4 million, the "whitewater feature" opened with much fanfare in 2011 — for one day. The city immediately shut it down when it figured out that its design had the unfortunate, unexpected side effect of likely killing anyone who tried to paddle through the supposedly safe bypass around the rapids. It sat in the river since then, unused, blocking canoeists, filling with silt and creating a slew of finger-pointing and legal threats among city staff until the City Council voted this spring to remove at least enough of the concrete so that canoeing Cub Scouts wouldn't be sent to Davy Jones' locker.
