Chilled

GF went to bed in expectation of his early start. This meant that he started to wake soon after 0200 and kept checking his watch until it was time to get up at 0430... (he'll suffer for this as the day draws on). It was -3.5C when GF left home. Crisp and dry - but very cold. The roads, despite this, were trouble-free and GF made good time on his journey watching the the temperature fluctuate up to -3C and down as low as -6.5C (near Newbury). 

It's morning like this that you are grateful for car heating, heated seats,  heated front and rear windows and heated rear-view mirrors.
