I am sure that they wouldn't do that. Now that 4 vessels have been damaged.
I bet the Coast Guard is having a h*** of a time down by the Columbia + Pacific.
Its called the death point. The water down there gets SO rough the coast guard bought a boat that can right itself if it were to flip over. Almost 60 vessels have sank in those waters.
This is actually in a lake but they had to close both floating bridged because water was getting on the road.
