I love riding in the dark.
#1 . When on the road for some reason I feel safer. I am well lit up and I know drivers can see me better, and I have noticed that. Especially the drivers pulling out of driveways and turning at lights.
#2 . Going on the bike path through the woods, where it is unlit, its very challenging as you really have to pay attention so you dont end up in the ditch.
#3 . Very few people are out and about after sunset and I dont have to deal with people walking and texting or headphones on not hearing my bell.
