After reaching the next lookout, we pause for a photo and I begin to rethink the wisdom of finishing the trail which continues along the spine of the rock fin pictured behind us. At one point the trail narrows to three feet wide with an 800 foot sheer drop off on one side and a 1200 foot drop off on the other. This is the exact scenario which triggers my worst vertigo and I have learned on this climb that the intense fear is also triggered when I see one of my children in a precarious position. Despite the fact that Nicolai has been on hands and knee since the chains began he stands ready to complete the trail as does Maya who is entirely fearless and part Billy goat. Although Kyle inherited my fear of heights he also wants to reach the top. Ultimately, I enforce a decision to stop here. Thousands of people complete this trail each month but I know I will be paralyzed by my vertigo and I cannot allow the kids to continue without me. I hate having this limitation but must accept it and be thankful for the many other gifts I have.
