I think this is pretty cool.  As a thank you from Microsoft to the community on our 30th Anniversary, admission to the Tech Museum of Innovation in San Jose is free on Saturday, September 24.  The Tech event is being advertised with a half page full color ad today and tomorrow in The San Jose Mercury News and radio ads are running on NPR.
