“I find a lot of junk in the river, too, the last few years,” added Thacker, four years older than his vessel and a resident of “Fort Chip” since birth. “Pipes, timbers. Last weekend, I was at the dock [at Fort McKay], watching an oil slick go by like someone was sitting up-current with a pail of oil, just dumping it slowly. An hour we watched it. With all these new oil plants along the river, obviously it’s coming from their places.” But even these are not the most distressing changes he has witnessed the past few years."
