I don't need anything fancy... and I don't want to spend 30 minutes looking for exactly what I want... so I just make my own.
If anyone is interested, I created a calendar in Google of the 2011 race dates on the Formula 1 calendar. Just the races with the location. No practice. No qualifying. No test sessions. And not even times. Just the races and their dates so I know which race is when and remind myself to be sure the DVR is set!
If you want to check this calendar out for yourself... you can do so here:
If you want to add it to your Google calendar, the easiest way, I think, is to copy the iCal URL above and paste it into the Add by URL field on your Google calendar. This is at the bottom left, under Other Calendars. Click Add and you'll see this field.
