i also print out a couple sources of weather before i go. i too use wunderground! i also use scoutlook. its an app for smartphones but can also be viewed online. i think its one of the best apps out there.

im also not big on surprises, so i check both the wisconsin and minnesota road construction reports prior to leaving also. its hit or miss on if i can find anything on highway 11 in canada, but most of it has been redone already between ft frances and atikokan in the past few years
