I have just launched a new website aimed at giving travellers of all descriptions, bushwalkers in particular, a means of leaving their travel intentions (aka route plan) online, to be delivered to a "trusted contact" if he/she has not logged in again by a designated time. It is an added extra to filling in that Ranger logbook that may (or may not) be checked from time to time.
As a bit of background, my wife and I conceived this idea when doing the South Coast track 10 years ago, after meeting numerous solo walkers from all over the world (God love 'em, especially the Israeli bloke we met at the base of the Iron *&%$#!, who had a 1kg block of cheese and a bunch of bananas). I doubt they would have told anyone what they were up to and 99 times out of 100 it would not matter. This website is dedicated to those cool people who, the 1 time out of 100, deserve to be protected.
Check out the site, if you like, and by all means let me know what you think of it. All feedback gratefully received. It is at http://myredflare.com
