You've never heard of barge shenanigans because it's a non-event unless you have an autistic hyperfixation on shipping. You can see the barges much more clearly in the replies. They're basically the riverine equivalent of trailers. It'll be a bitch for a day or two, and somebody's gonna get a tasty government paycheck wildly overestimating repair costs, but an attack on infrastructure this is not. You'd get better results downing a few trees along the freeway.
