I usually leave the house at five forty am. Though it is not as light as it was when I first started commuting back in March, the dark does not bother me. Now the problem. My daughter has asked me to go to a spin class Friday am. The class starts at 5:15am. I would like to commute by bike that morning, but I would have to leave the house at 4am. I do not feel comfortable leaving that early. I am not sure why that bothers me as I leave in the dark now. What time do you all leave for your commutes in the morning?
