^^^ If the docks have lines painted there should be no excuse for being crooked, unless the lines are crooked, lol.. I go to some warehouses where there aren't any dock lines and it can be difficult to square up to the dock without them. I have only been driving for 39 years myself so maybe I need some more practice, LMAO.
Nope, no lines! Sometimes I think that looking in the mirrors can throw you off somehow. You think that you're straight but in fact you're not. This has happened to me more then once.
