Spent lunchtime today double checking the GPS co-ordinates for my second geocache. I am mildly hooked on caching (insofar as I can be in this city, avec toddler & sans car). Cachers tend to be drivers, and even those caches in a town are almost completely devoid of public transport information. So my caching activities are pretty much restricted to Edinburgh, which has three caches in town (by next week, there will be four). I’ve visited one, and will be looking for another on the 11th.

I constructed the third one myself over the last four months. I’m actually quite proud of it. It maps out a six-stage walk through Edinburgh’s Old Town in the footsteps of Burke and Hare. As the searchers go from place to place, they have to look for numbers carven on gravestones, into buildings, and on plaques. The numbers then assemble to make up the GPS co-ordinates for a final location where there’s a grim historical relic. The cache has an E2 connection as well. One fellow noder, nine9, helped me pick some of the locations, and two others (fuzzy_and_blue and Jongleur helped Mom test it. Only one other person has hunted it thus far (Silver Fox, Edinburgh’s only other geocacher), but I’m hoping people will come up for the Edinburgh Festival and spend an afternoon on it.

This second cache is less public — it’s on a footpath that is not at all obvious from the streets nearby. I think non-locals will have trouble finding their way onto the path. Martin and I didn’t realise it was there when we first moved to a flat three blocks from it. Once we found it, I used to walk home from work that way in the summers. It was a secret place, hidden from the main flow of Edinburgh traffic, and I was sorry to abandon it when we moved again. It’s also the gateway to other secret places, such as Warriston Cemetery, with its population of, erm, romantically inclined men.

While I was out scouting for the cache location, I saw my first warchalking mark. Martin told me where it was. I’d walked right by it on July 6, and would have done again if I didn’t know what it meant.

It all makes me wonder what other things are stashed along the path, in holes in the walls and under rocks. What else is hidden around Edinburgh? What of all the graffiti and scribbling on walls is more than it seems? It’s the fascination of spying, of tradecraft but there’s something deeper.

I partake, to some extent, of those family characteristics that get diagnosed as Asperger’s syndrome when they occur in full measure. Some of that is an inability to read the signs, to find the secrets of other people. After all the trouble I have with social interactions, I’ve come to like secrets I can unravel. I wish I could find the GPS location of a hidden agenda, or a glossary of the markings that advertise the truth.
