Payments Geeks on a Plane - Where Would YOU Want to Go?

Let's have some fun! A friend of mine, Dave McClure, is currently touring China as part of his Geeks on a Plane tour - a visit Dave and some friends organized to take "10 day orientation tour of Tokyo, Beijing and Shanghai's Internet, Mobile & Gaming sector." Among many other roles along the way, Dave led PayPal's initial efforts to build a developer community.

Let's say that we put together a tour for payments geeks on a plane. Where in the world would you want to go? - to see who and what specifically? Or, if you'd want to host a visit to your company - tell us what you'd show us and why it's important!

Let's have some fun - you can either comment here (below) or over on this thread on Friendfeed where I've started with a quick SF Bay Area tour kickoff beginning at PayPal.
