This virtual tour of the Kalalau trail is quite impressive, and especially for those of us who would like to hike the trail, however the "OVER THE EDGE" section keeps many of us from embarking on the hike (myself included). See the following link for a closer look at this sketchy part of the trail. Would be interested to find out if there have been any improvements to the trail.
