Questions to Ask at Recruitment Events

[barilicious]

Starting next weekend I'm off to start visiting some of the schools in to which I've already been accepted. I'm not quite sure what to expect going to these recruitment type of events and what I should ask/be prepared for. I contacted POIs and graduate students with similar interests as mine back in September/October before I even applied to any schools - so I've already asked a million questions before I did my apps. Nonetheless, I'm starting to compile a new list of a million questions of I want to ask during my visits. Therefore, what are questions that you think are pertinent that I ask, and what all should I be expecting during these types of visits? Thanks for all help & advice in advance!!
