Are there any worlds you never use?

I almost never use Evergreen Harbor. The only time I had any played sims living there was back when I first got that EP and was doing a couple of test saves. I'll probably eventually find story reasons to use the town; I already do on rare (very short term) occasions. But for now it's my least used one. Well, of residential worlds, that is. My very least used one is Granite Falls.
