I found a different route because many times these big trucks just don't get a clue. I sure hope you find a better route! Altough some trucks do give me some room on some of my route. But one part of my route I had to change due to some close calls. Takes me a little more time getting home but at least I don't have to deal with that crazy area. Some people just think that when you have signs bikes can be present. I belive that they should either sign nothing or sign everything... The in-between just causes more confusion for the motorists.
