I have a friend whose husband's sister got married in Toronto a few weekends ago ... right in the middle of the G20 summit. Like the bride in this story, she had booked everything ages ago, long before the G20 meeting was announced, and a couple of weeks before the wedding found out that the church they had booked for the ceremony was within the security perimeter and they and their guests would not be allowed inside the perimeter at all. They had to scramble to find another downtown Toronto church (at the height of wedding season!) and rearrange all their plans. Unfortunately, sometimes it happens. I do, however, totally get this bride's irritation and frustration, especially as she can't get any information or even confirmation that it's going to happen at all, so she can't really make alternate plans. I think the whole "Chelsea Clinton ruined my wedding" thing is a bit much, though -- it implies a nastiness or unpleasantness on Chelsea's part that I don't think is appropriate.
