First of all, let me thank the committee for inviting me to appear this afternoon.
Mr. Holland, I wanted to complement Mr. Elcock's earlier answer by saying that G-20 summits, by definition, have all been held in urban environments because of the number of participants and because of the infrastructure exigencies associated with holding such multi-faceted summits as the G-20. We've had London. We have had Pittsburgh. We will have Seoul. So it is the case, in fact, that the cities that can actually receive such summits are, by definition, highly urban environments.
