600 guests and 14 Bridesmaids sounds excessive to me, also.
"Big" weddings are a common thing here where it isn't unusual for 4 generations of a family to be living in a community. Big would be defined as 200-300 guests.
When both the Bride & Groom live in the same community and went off to college where they developed another big circle of friends, these occasions tend to grow. But NEVER to 600.
Both of my older boys were married in front of more than 200 guests. That's not unusual here. Actually typical.
I've never been invited to a wedding where there were 600 guests. However, I have been to cattle shows where there were that many attending. Hmmmm.
Will Mr. PB be attending the World Pork Expo? If so, is there a possibility you will be traveling with him?
