Actually Sarah did say that, and Tina Fey parodied it on SNL
Exhibit A:

No Palin said you can see Russia from Alaska and you can at times and in certain places. Been there, done that.
She did not say you can see Russia from my house. That grew out of her comment that being so close to Russia and dealing with them on trade etc gave her more foreign policy experience then Obama. Again true.
EDIT: Here is a little backup to it.
