You may have to have a google account to view. It's the calendar at the top, entitled 2008 Columbus Crew. If you're logged in you'll be able to add it to your calendar. Please let me know if there are any errors. Got the preseason AND the national TV info. Go Crew!!!!
Crew Union has a google calendar that will be updated with locations of viewing parties for the Crew and US games and any other events for those interested, it's also on the Crew Union website if you don't use google.
