Is it possible that man may be able to colonize Neptune someday?

What do you think?
Mabey, if the colony was in a station orbiting Neptune, it might be referred to as "The Neptune Colony". Actually being on the surface, under the atmosphere, floating on whatever is down there? That would be very hard. Ms. Sue's link should show you just how hard that might be. Would it be worth trying? I leave that to you.
