I recently did a Sync of my iCal calendars between my MBP and my iPhone.
It's been awhile and I got that standard message that states that syncing the two will change more than 5% of the events on my computer. I clicked yes and went about my business.
I just opened up my iCal on my MBP and there isn't one calendar event in the history of iCal (months back...months forward...today...nothing)....however there are still a massive amount of events on my iPhone (as there should be).

Why didn't the events on my iPhone's iCal import into my MBP's iCal?
