If you’re a Sabres fan and not able to run ruby scripts you can download the iCal version of the Sabres 06/07 schedule here for importing into your favorite calendaring program. For some reason there are some games missing in the source Excel spreadsheet so unfortunately they will also be missing in the iCalendar version. I don’t make any guarantees to it’s correctness so if you find an error or miss a game you’ve been warned.
