Almost on saturday. I was riding some singletrack at Saratoga Gap and this guy was going something like 20 mph and I was going 10 the other way. There was dirt and bushes on my right side and steep fall into trees on his right. when the guy saw me he started braking and almost lost control and fell over the edge and I scraped the bushes and held steady. There was barely enough room there for one person to ride, and speed limit was 15 mph. The guy was apologetic and pretty shaken, but I was pretty tired after long climb and didn't say anything.
