If you take a look at ChristinaL's "Best/Worst of Dorms" forum post, that might help!! -- http://go.butler.edu/cs/forums/p/1014/1658.aspx#1658
I lived in Ross my freshman year, and I absolutely LOVED it. Everyone's really nice and sociable, and the boys are only allowed on the girls floor if they're escorted (the girls have a special key that gets them onto their floor). I had a blast in Ross, but I know that all of my friends who lived in Schwitzer loved it. It's usually pretty easy to switch if you're not happy once you're here. Let us know if there's anything else you have questions about!
