This link takes you to the global site information for Innovate conferences around the world:
http://www-01.ibm.com/software/rational/innovate/aroundtheworld/
The US tour basically starts in Dallas on 8/22:

The Dallas link to register is broken - sorry - look for the link at the main site above.
Can this be incorporated into the events calendar?
