Sourdough,
The great moment for angels occurs in Milton's Paradise Lost, the great shifting moment in Western culture during the 17th century, the moment when Satan becomes more interesting than God. From that moment on -- reaching something of an apotheosis in the "Wings of Desire" or in any doomed poet of our acquaintance -- the idea of heaven as the holy place is replaced by the idea of the earth as the potential holy place, and the fall of angels -- angels flying too close to the ground, angels choosing earth life over heavenly stillness and barely surviving the crash -- becomes the centre of the desire to transform the everyday into the eternal, while not losing the everyday -- the aching of never, the bitterness of failed hope, the joy of food after hunger (all those things that God cannot understand). Dark experience, the voyage into and out of hell on earth becomes the journey to enlightenment. Wilderness and desert replace paradise and the golden city. Therefore, "soured angel on wheels".

My advice: Don't stuff it. Get a map, or make a map of where you have been, about the size of your biggest floor. Put the written fragments of your journey on the places where you have been. Sit and look at it for a few hours. Add the trinkets, photos of all the rest of the places. Then fill in the lines and spaces you haven't written about with more writing fragments. Put it all together and a condensed version of the map into a binder. Then sell it for large amounts of reward, like Mudcat adoration.
yours, Peter T.
P.S. Please remember I am joking about something serious.
