Everything starts with a pub-tour.
Couple of drinks, couple of cigarettes, off to the next bar.
Couple of drinks, couple of cigarettes.

Then - moving on.

Next day, same thing.
Couple of drinks with a couple of cigarettes in a couple of pubs.

In each of the pubs we leave behind a nice silvery lighter.
Each silvery lighter equipped with a nice little transmitter and its own transmission id.

And above the roofs antennas rise.
The next couple of weeks we spend roaming the urban habitat, tracking the lighters,
tracing the fire; logging its every move.
