i did hear the same at stn.....they did a 75 -25 de ice mix ...water being the 75 bit....ho ho ho.
still on wednesday night at stn they did de ice and they gritted the car park and the walk ways....it was +2 degrees all night with rain and drizzle....no sign of ice....still the thought was there,you cant get it right all the time.
and i dont think you could bring de ice fluid through in 100mm bottles as the substance sniffing machine in security would pick it up............joke.
