At my new workplace.
I found a nice place that is worth hosting a geocache.
All I need to do is go to the given coordinates and do a quick calculation.
How many country flags can you see inside?
And now the quick calculation.
Listing koord
north + 3 times the summary of flags
west + 8 times the summary of flags
Have fun
