I'm a graduating student at SLS and am delighted everyone seemed pleased with the ASW - we certainly enjoyed having you here. If there are any specific questions you have, please feel free to ask. I'll be around this site over the next day or two.
One thing that did occur to me: I chose between HYS and, while it was a difficult choice at the time, I've been immensely grateful ever since. I can't imagine a better place to spend 3 years.
Having read some of the above comments, I'd like to make 2 quick points:
(1) You don't need a car (unless you have a family, of course). I cycle everywhere, and a lot of my classmates do likewise. The weather is typically beautiful, so cyclying around campus and PA is a joy.
(2) You aren't giving anything up academically by choosing SLS (especially over HLS - the opportunities from there are pretty much identical to Stanford). The only shortcoming would be against Yale with regard to clerkships and academia, but I'd like to emphasize that Stanford does extremely well on these two grounds as well. As for law firms, you can have your pick.
Any questions are welcome. Best for now,
