Documenting an adventure makes it more memorable and will help to inspire more people. Pannier.cc have an excellent site that revolves around exactly that and will be running a workshop to showcase best practice, from journal writing to photography and perhaps even a little film making on the move.
For those that aren't familiar with pannier.cc, they are definitely worth a follow even if it's just for some daily inspiration. As part of their website they run an online on-stop shop for all things adventure cycling, with a whole range of products you wouldn't find in any normal bike store.
