cldisme:Umm... I make sure I have fresh batteries and a memory chip in the camera?
I only "prepare" if I am aiming for a specific icon - usually when going to a place that I am not likely to return anytime soon. I research any categories that are unique to the area (historical markers, architecture, etc.) and plot any un-posted candidates on a map. Then I make sure I find time to travel to that unique location. OK, so I spent an hour and a half traveling the Tubes just to find a London Coal Tax Post near a stop - when will I be in London again?
Otherwise, my waymarking is happenstance... ethereal... organic... random... when the muse hits me...
Lately, I find myself preparing to go someplace and end up someplace else in the same area.
