Yeah, with decent lights it's a blast...I love cutting through the still of night!. you can see traffic much sooner because of lights so I feel safe, as to safer, I'll sit on the fence there! there's much less chance of traffic incidents as there's less to zero traffic. I've taken on roads I've not cycled before in the dark this week and enjoyed it and tackled off road terrain on my road tires( with the moon breaking through some cloud, even at slow speed, it felt like a great cycling moment). You feel like your going much faster, especially on dark cloudy nights, were your light ends your vision, I find it raises my adrenaline, makes me feel sharper and more focused. It always feels daring being in the middle of nowhere in the dark of night and I find it challenges my confidence as much as my bike handling. There's something awesome about encountering nocturnal wildlife too. Usually I pace myself a bit slower at night, but put some effort in tonight, other than the descent which I whimped out on. I always let some one know where I'm going and when I expect to be back...as is good sense.
