I don't know why other book producers don't follow suit. It has so many advantages: page marker, double layer protects the inetgrity of the inner pages (by being slightly proud of the page edge) and gives the book a more 'solid' feel, it allows you to have a whopping 3 page internal photo spread, and some prime advertising space.
I copied it from the Cresciano guide.
Glad you got better weather on Sunday. Saturday was very frustrating, I woke up to heavy rain, then I waited until late to go out, only to have it piss down just as I arrived in the Pass.
