Brilliantly bright blue sky, but two annoying drivers to deal with. The first tried to pull up next to me at a stop light, in his huge F250 with dualies. Ended up halfway in the other lane (4 lane road) and then almost ran into me as he pulled away at the green light. The other was a cement mixer that did the stalking thing for most of a mile until my turn off. Why he wouldn't change lanes is beyond me.
