Today we released an improved version of our iCalendar feed that supports popular web calendars like Google Calendar, Yahoo! Calendar and 30 Boxes.
Although we've tested with these services, any service that understands iCalendar or RSS feeds should be able to read in our calendar listings. If you search, for say track events within 300 miles of your zip code, before clicking the calendar link, you can subscribe to just that subset of our calendar.
You'll see the new Google and Yahoo! links whenever you're looking at an individual event on the public calendar. Logged in users will see this in the next day or two.
Many thanks to Jauder Ho for his help with finding and resolving this issue.
