My friend and his son went from Edmonton to the Pass for New Years to visit his sister. He was on 22 south and was telling me of the wind signs they have on the highway. Sign said gusts up to 186 km, wow. Then he said, they seen up ahead of them and on a curve, a dodge ram pulling a 18 ft single axle old rv. The trailer went up on one wheel first, then the trucks right side wheels went off the road! He said that driver was able to save the rig and got all wheels back on the road, then pulled into the ditch. Probably to change his shorts.
Now thats wind gusts.
