David Daniel is one of the unlucky people who happen to own property in the path of Trans Canada's southern leg of the Keystone XL pipeline, which will extend the existing Keystone tar sands pipeline to the Texas gulf coast refineries. He was interviewed by the NPR program "All Things Considered". One trip they made was to Michigan, to see damage still there along the Kalamazoo River, where another pipeline carrying the tar sands oil ruptured two years ago.
The NPR page contains the story in print, and a link for the audio from the program.
In Michigan, a cleanup worker turned whistle-blower named John Bolenbaugh helped answer one of Daniel's questions: If there's a spill, will they clean up all the oil? ... A couple of minutes later, he walks out of the river, holding up a blue latex glove covered with tarry black stuff.
