I tend to make my way down this trail quickly. Whether I go faster than others or if I go slowly the trail can be dangerous with all the rocky points jutting out of the trail. One moment where I take my eye off of the trail can mean the difference of my foot landing dead on that point or getting just part of the point and spraining my ankle.
I noticed the red LED turn on in his camera signifying the flash was ready. I figured out what he was doing and told him not to think of letting his flash go off on me again. I could care less if a photographer wants to photograph me. However, the fact that his flash is ruining my night vision when it was getting rather dark out really upset me. I asked this guy where his trail etiquette was. I also asked him what he would be willing to do should I twist my ankle due to his negligence.
Sorry for the rant. Carry on with your regularly scheduled hike
