I went to this as a grad student. Just awesome. If you have a chance, go. As with so many things the actual competition for access to top intellectuals was limited.
Had lunch with Mirrlees; a walk by water with Doug North and a series of heated debates with Clive Granger and Bob Engle. If you talk to them, they will talk back.
The exception was John Nash. Surrounded by people and didn’t say much.
