I could have a million zip ties and I'd still get off and have a look around that corner!
Several years ago, I was riding at the Lee & Cragg quarries in Lancashire (UK) with two mates. One had a mechanical and the other was helping him fix it, so I went exploring. I followed a sheep trail that gradually brought me to a huge gash in the terrain. I was steadily approaching at an angle what looked like a 100' sheer drop to my left. To my right was a house sized rock perched close to the edge of the drop. The trail went alongside the edge of the drop and squeezed between the rock and the drop. To this day I can't imagine what I was thinking, but I kept going. As soon as I went around the corner, I knew I was in trouble. The edge veered in towards the rock and the gap between the rock and the drop narrowed to a bit less than bar width! I didn't have enough room to get off the bike and if my grip touched the rock, I'd be down that drop to a very messy ending. I considered going off the back of the bike, but thought I might lose the bike. Being a tight Yorkshire git, I rejected that and kept going. A cascade of thoughts flashed past in a second. Fortunately, with a tiny bit of bike lean left and body lean right I got past the choke point. A few yards further on the crisis passed and I dismounted and threw up. I have never forgotten that event.
