At night times, when there are very few cars, I feel more relaxed; CREE XML T6 1200 front, CatEye rapid 5 tail, reflective vest with reflective armbands help keep me visible. Plus, it is really pleasant at night times because riding on a summer day in New Jersey is HELLISH. You've just gotten outside and you are already sweating.
The only problem I have encountered is people. Bike riding (especially night bike riding) is a priori considered to be extremely dangerous, although yet all the drivers I have seen were really nice to me biking.
Oh, and also I had not heard so much crap when I was getting a tattoo, as when I decided to commute using a bike.
