The best country to watch the solar eclipse would have to be in Japan because the total solar eclipse will happen nearest to it, somewhere 100 km southeast of Japan.
So if you want to experience the best solar eclipse on July 22, 2009 - go to Japan or maybe just watch the 2009 solar eclipse live stream provided by various websites. Just check out that link.
Personally, I agree with my friend that a solar eclipse in America may be boring to watch so I'll just settle for the 2009 solar eclipse photos that will be uploaded on Flickr that day.
