I was already planning a visit myself, though I haven't RSVPed yet...but yeah, the voucher is pretty sweet. Tulane seems to be doing everything right... the voucher, and they already had a current 3L email me to talk about the school, and we ended up chatting about it on the phone for like an hour. Their admitted students website is also nice.
At this point, the only concerns I have are Katrina related, and the possibility of more hurricanes in the coming years. One other thing is it being in the South... not sure how racial tensions are there (my gf is Korean, and I worry a little about her visiting or staying there, seeing as how there are very very few Asians there... I see on your profile that you're Taiwanese... do you have any thoughts or concerns about it?)
Judging from your list of schools, seems like you'll likely be choosing between the same two I am: Loyola and Tulane (unless you get in at George Mason, or I get in at Fordham PT). Do you think you'd go choose Tulane over Loyola?
