A few hours ago I was driving from Montreal to Tremblant with my family. 20 minutes in, I hear a loud noise from the roof, and everyone starts yelling at me to pull over. Turns out the ski rack popped open and all the skis flew off into the busy highway. No idea how, but nobody else got hit. All the skis got pretty messed up, but are probably repairable.
The point here is that the situation could have turned out much worse. I'm not really bummed out because nobody here got hurt. I checked the rack before we left too, but I guess cold weather does that. So, always make sure that everything is in place to avoid a situation like that. Dangerous stuff.
