There are some trails I ride on regularly and I've seen many people go each way. A few times the single track gets very narrow and I was wondering what should I do when I see a biker coming towards me? There is also an about 50 foot cliff on one side and a fence on the other so I wouldn't have anywhere to go. Should I turn around and go back to a section that was wider and let them pass? Otherwise the trail is too narrow and won't allow two bikers side by side.
