I'm sure everyone else will jump on ron's error, but I might as well too.

The L5 point is not between the earth and the moon.  That's the L1 point (I
think).  L4 and L5 are in the moons orbit but 60 degrees ahead and behind
(I forget which is which).  

I thought that it was decided that the L5 point is not where you want a 
space colony; rather, there is a two week orbit that can be reached
from L2 (the point behind the moon) with a velocity change of as little
as 30 feet per second, making lunar materials very easy to move.
