If you take the 2300 point of view where Texas went its own way, I think it would argue for the 49th being more or less still a going concern: and *very* believable.
If you go to the State House, there is the lobby there in the inside. On the Centre of the lobby floor is the great seal of Texas, arranged around it, is all the other people that at one time or another claimed Texas as part of it: The US Seal is no larger or smaller than any of the others - with room for more.
Always thought it was a clever way to say something without actually saying it.
