You have no idea what it takes until you start preparing for it. I mean ... I'm sure once I'll be on the road I'll realize (once again) I had no idea what it took.
What am I talking about?
Through the month of September, I'll be going home, by bike. I've written about this before, but now, I started preparations and the more I think about it, the more things I have to do ...
... and it's lots and lots of things, like itinerary, necessities (like dry food, first aid kit, toilet paper, toothbrush), GPS, maps, saddlebags (which I still have to buy) and so on.
