Not the best title for what I am trying to convey but seeing that our trail systems do not have any emergency routes I thought this was a useful post.
With the leaves off the trees and the ability to see for far distances I would make the suggestion on your next ride to look uphill-downhill and across valley. Study the surroundings, Make notes of how trail may only be 50 yards from a quick escape route should it be needed. It's amazing how a trail like GF doubles back on itself quite a bit and getting to a road or short cutting a trail to alleviate a 3-4 mile hike out is fairly easy. I have had my fair share of assisting hurt and lost people off the trail, Trail knowledge and simple short cuts can make a big difference.
