Driving to work in a heavy downpour recently and I came upon a flooded section of road - essentially a dip in the road with water running across and probably around 6" deep. So I ploughed through it at I guess around 20 - 30 mph and made it across fine. When I got to work I noticed that all the aerocovers were missing so immediately thought they'd been stolen, however I Googled a bit and found someone who had posted about losing them when going through floodwater. Sure enough when I returned home and looked around the area of road concerned I did find several remnants (evidently broken up by the traffic) and one complete cover. This is obviously a lesson for me to be less gung-ho with my pride and joy, but also a cautionary tale for others who may be tempted to do similar. Certainly it's not something that's mentioned in the user manual!
