   No, that's Serigo's game.  One needn't have been on Mars to know   
   something about the geology any more than one need to have been to the   
   bottom of the ocean to know that it's wet.

   Any colony will 'start small'.  They will be able to get metals in   
   quantities sufficient for use by the colony for some time to come.   
   We're not talking about trying to support hundreds of millions of   
   people the first day and it's supporting those sorts of numbers is   
   what leads to those "huge holes".
