Last time I rode the local bike trail at night I came upon some teenagers laying crossways on the trail in the darkness looking up at the stars, I nearly ran them over. Marginal light, a bit too fast, and they were all wearing dark clothing. We were all having a nice quiet time on the trail, me riding a bike, them laying on the ground looking at the stars, then five seconds of hard braking, tire skidding, people screaming and laughing, a couple mutual "'scuse me's", and all was peacefull again.

Riding at night can be a pleasant experience occasionally interrupted with moments of terror and panic, then pleasant again if you survive.
