On a computer, go to your Google Calendar.
In the left column, click the boxed triangle next to Other Calendars and select Add by URL:
In the popup, copy and paste the following URL: http://openairbigbear.com/events.ics
Leave other settings alone and click Add Calendar.
Now your Google Calendar will sync with all Open Air Big Bear events.
Note: It may take up to 8 hours for the events to populate your Google Calendar. Unfortunately the Calendar URL must be manually added (follow directions above) at this time.
