I did not bother to read all the posts. Why? Because I have beer to drink and games to play wile drunk damn it!
Anyway, I don't think we would need to sweat over the upkeep of tow or three carriers IF we can throw our own products at it. Like for instance, you call up us rock radiers and say "We need enough shit to keep our carriers running!" Cool! We go mine and turn all that ore into stuff needed to keep the carrier(s) flying. Also leave some kegs for us as a thank you after words, thanks guys!
