Update: I don't have to work tonight, so if anyone wants to show up earlier, I'll be hanging around the Hood most of the night.
EDIT:
Here's what we do:
The mining ships shoot the rock, the trader's tractor it and head to New York. They'll sell the gold ore at Detroit munitions AND SEND ALL THE MONEY TO ME! Then, pick up Luxury Consumer goods at New York and take to Planet New London. Sell there and pick up Mining Machinery. Sell on the Hood, return to the mining site and pick up more gold.
All money will be divided evenly between everyone there. If you're not happy with this, don't bother showing up.
