I'm right there with ya.
I'm 24 weeks and we are moving cross-country near the end of the month...with a pukey cat, for a 30 hour car drive...with three people.
It is going to suck royally :-(
And I've been getting serious nesting fever, too, but when you're trying to downsize, buying stuff has to wait til ur settled...so I keep just dreaming and planning and wishing and waiting. It's killin me! :-P
