Well AAARGH and all that...got me street sailor's license in a snowstorm and once navigated the northwest passage (that's the NY State Thruway from Schenectady up to Oneonta) in a white-out type blizzard where the only way you had to navigate by the lights of the ass end of the cars ahead of you. They went floop in a ditch, and you went in some other randomly selected direction. Ah yes, I've paid me dues...and I'm not stupid enough to try that stuff again! (But the weather looks rather wimpish right now.)
