I run a big loop from the New York system to Dresden to New Tokyo to New London and back to New York. I know there are shorter more profitable routes (I make about 10-15mil per hour) but my character prefers to see the sights and venture off on tangents now and then.

to subjugate the enemy's army without doing battle is the highest of excellence."
