Aside from making an appointment with her, you should e-mail her, introduce yourself and give her an idea of what you’re interested in. You probably won’t get a full idea of what she’s like, but you’ll have an idea. Get a feel for her as best you can on e-mail, follow her on twitter if she’s on twitter, Facebook etc. Also, if you will be visiting for more than a day and definitely confirmed with her that she will be there that week, ya might wanna take the 1st day to talk to her if she has no appointments or gets called into a lineup. No pressure, play some pool, have some drinks with her, relax, no stress, no nervousness, no pressure. You’ll have a good idea b4 then.
Good Luck!
