I agree with that, sometimes you get direction on community boards telling you where to go and the direction could be something like: "Go straight 500m until you pass a massive rock, then go left and take the right-most trail head after you pass the big coniferous tree.

GPS coordinates are a miraculous thing.

I would really like to do a solo trek one day. I feel that being alone with one's thoughts and the utter serenity of the outdoors would be extremely beneficial for your well being. But I'll just stick to my Canadian wilderness where the gators can't go. :)
