First of the Frost

Not liking this....   It' probably more accurate to say that this is the first time I've noticed frost - I'm not known for getting up early ;-)   but  I had to this morning.  

Lines of course are where the grass is cut.  So is it warmer where the lines overlap - and where there is slightly more grass ?    Anyway, It was cold today!  The funny thing was the sun was splitting the skies most of the day.
