Once on a very windy/rainy day, a big truck carrying what looked like a big shed on the back that was one lane over and almost blew me into a ditch going 30km/h. When it's really windy when I ride, it blows me alll around the road.. I have to tilt my body like I'm going around a corner (like a 70-80 degree tilt, depending on how storng the wind is atm) just to stay up and not get blow off my bike, and to go in a straight line. It sucks eh?
