Well spotted Error, I make it 2.4 kg. I often wonder about the extra weight myself.I do know I could squeeze even lighter. I have now updated the gear list and it is 4.88kg.
I don't do overnighters and wild camp most of the time - the national trails-week most of the time week treks or a few weeks- some abroad therefore to avoid hunting for anything my FAK kit is comprehensive and includes,strapping tape, suncream,and a few ointments,(some would consider these consumables and not add them in).Similarly my cook kit of esbit tabs,Flissure Caldera with Inferno wood burning inset is all encompassing so I don't need to hunt out fuel very often but is also belt and braces.Also Teva Barracuda camp shoes and my techno stuff sac with smart phone(GPS) MP3 and chargers brings up the weight.
To put some detail on my gear weight the large items are MLD Wild Oasis tarptent, Zlite ArcBlast backpack(52Ltr),WM Summerlite sl/bag, 3/4 Klymit sl/pad (I use this inside the sl/bag), MLD Superlite bivvy.
Looks an interesting read especially if the local history info is kept up throughout. Why no cost information? Unless it is very cheap it is likely to be bought as a gift for a walker.
IMO If you are long distance walker you are unlikely to buy someones else's journal as you have had your own experiences and mini adventures; much the same I suspect as yours.
I have recently read Cheryl Strayers Wild which is very well written and weaves her family thoughts and experiences into the PCT story. I have also read Rushos Mystery of Everett Reuss which has a lot of info from his letters home.
These books show what is going through their minds which is usually more interesting than the views they saw..
