Money Changer Traditional Cache
Brendano: Well, I did have plans to resurrect this cache, but it has been a while. If I do eventually put another cache out, I will make sure to make it just a little bit harder.

First, find you way to a common Mafia meeting place at the above coordinates.
From here, the final location is encrypted. To determine the coordinates, count the number of maroon window shades on the building to your north. This is AA.
BBB is the number of wooden bars above your head (including the shorter ones, and counting the longer ones as just one).
A quick check that your calculations could be right. Add up each of the digits in the two numbers (AA and BBB). This should be a multiple of ten. (In fact adding up the digits in AA and BBB individually will also give a multiple of ten).
Now on to the money laundering, but first a few calculations.
CCC = BBB + (4 x AA) + 17
DDD = 2 x (BBB + AA + 2)
Having done the calculations, proceed to the stash at 27°28.CCC' S, 153°01.DDD' E. If you have your calculations correct, it will be about 200 metres away, near a building where a lot of money changes hands.
Remember, you will be under tight surveilance as you attempt to retrieve the cache, so you will need to engage sleath mode.
The cache is small and black with GC scratched on the lid. Please do not reveal the identity of the container in your logs.
