Was fun, i shall now do this every time i'm out.
One observation i made is that its very easy if you have a good map and already know what the important landmarks in the area are, so you can identify them on the map. If i was dropped in the middle of a foreign country.....it would be MUCH harder. Still, a very nice skill to have.
Also, thanks completely useless govt rangers/foresters that should all be fired for not marking fucking anything. If it was not for your complete laziness and contempt for what you get paid to do, i would not have been able to larp as well as i did.
