when i was driving into work at about 12.00 in the afternoon there was one of those big green street signs near the airport. When i was about 200m away it lifted up into the air and blew about 100m into the airport, luckily the wind wasnt going the other way or it would of landed on the road. also there was dust everywhere it was like fog i couldn't see anything in the distance. then it rained, now my car is really dirty .
