Kofferspiele
If you look at what you need to run away, you might be surprised how little that is. For me I think a second pair of underwear, some warm socks and a t-shirt are essential. If you wash them every day, you can go a long way. Further: a toothbrush. Soap would be nice, but you probably can find it along the way. Then there is the smaller of my cameras with the 50mm. With that you can't do everything, but everything that matters. Also my beloved fountain-pen. A pencil would do too, but the pen is nicer. At last a notebook. Everything else on top of this would be just pure luxury.
