When I'm towing, I either do the speed limit or go with the flow of traffic, whichever is slower. But there's one stretch of highway around here
which has a reputation of being dangerous. One time on this particular highway, some goofball was tailgating me and decided he didn't like being behind a big trailer, even though I was doing the speed limit. So said goofball pulls out to pass, without checking for oncoming traffic -- and of course there was. The guy cuts in front of me, I'm standing on the brakes hoping that I don't jackknife and end up in the ditch or worse, the oncoming car is heading for the ditch himself to avoid a head-on, and the goofball almost clips my front fender. No accident, and the goofball was just some taillights in the distance.
And that wasn't the only time that has happened. But we no longer drive up that highway; the campground we went to there doesn't suit our interests anymore.
