I had a great ride in this morning but I am realizing that in the dark morning with only street lights (some of which are off which was especially unnerving on a recently paved, extra black asphalt street), I should invest in more than the bright flasher I have on the front, one or two decent lights. It was 6C (42F) but I rode extra hard (I haven't checked my computer so I don't know if the effort will show up in reduced time) and enjoyed the ride more than usual.
It was slightly misty/foggy at parts and strangely so. Earlier this summer, it was an especially foggy day but only in the low areas (especially on the roads around St Charles Lake where I could barely see the road beneath my wheels): the higher areas were clear. This morning, it was the reverse where the top of hills were foggy and furthermore, the fog was warmer than the clear regions. At one point on the unlit 1km dirt road between a residential area and the university, it rises to a hill and for about 3-400m(yds), my glasses were so fogged up, I had to remove them because I couldn't make out the road and my front blinky wasn't helping light up the path at all.
Looking forward to a nice warm (23C/73F) ride home in the sun.
