There's an article at SeekingAlpha.com revisting the Seaway Reversal. Like me, the author thought that the Seaway Reversal would be completed sooner than later.
The author at the linked article above concentrates on one issue: the Bakken exceeded expectations.
There was less written about the Seaway Reversal itself. RBN Energy provided a great update on the pipeline reversal which explains the other half of the problem.
There is a tag at the bottom of the blog, "Seaway," which aggregates articles concerning this issue.
For newbies, this is where I track the spread.
