Well I decided to ride on Monday due to great weather today, and storms likely tomorrow. But our staff meeting on Mondays is now at 7 AM instead of 8. So I had to leave the house just after 5 AM. It was dark for more than half the ride, where usually leaving at 6 it's already starting to get lighter at this time of year.
Of course in 2 weeks after the time change I'll be back in the dark for most of the morning ride at 6 AM. If I decide to go at 5 on Mondays it will be dark for nearly ALL the commute.
The plus side was super light traffic. I think I had only 6 cars pass me in 15 miles, and 2 of those were right by my house and 2 near the office. So for the majority of the ride only 2 cars passed me.
Also one of the 4 way stops where construction has been going on for months now has new traffic lights up and flashing. So that will make 5 traffic lights on my commute, where 1 year ago there were only 2 lights.
