I've been using this personally and thought that I would share with the NorCal racing community. I wrote a tool to scour the NCNCA Road Calendar page to generate an iCal (.ics) calendar for import to your favorite calendar application (Outlook, Google, etc). It also groups the most recent open registration links on the page. I'm hosting it on my site as it has the software to do all this. The Calendar subscription and the page are automatically updated daily to reflect any changes made to the NCNCA calendar.
