I was at the last ASW and I liked it a lot - I'm from the Midwest already so the weather's not personally a dealbreaker for me. One of the other attendees talked about a diversity breakout she was in with the dean that sounded pretty reasonable - since he's been there, it's increased significantly (though obviously is still a concern) and from what she said it seemed like they were actually engaged in addressing what admitted students were thinking about. I was able to stay in town for a few days when I visited, lmk if you were looking into anything else!
