Parents - when you meet up with your new Plebe right after the Induction ceremony, take something to sit on the grass with - I suggest a vinyl/flannel backed table cloth you can buy at the dollar store in case the grass is damp, no one has to suffer the indignity of a damp behind. You can pitch it after you're done.
Also, take a snack for your new Plebe. My DD had a late check-in, 9:15 last year, and with all the rushing around, didn't even get to eat anything until dinner was served after the ceremony. She was famished and we didn't have any snacks for her. Many of the Plebes were given a lunch, but the late check-in kids were told they didn't have time to eat, so they weren't given any food! Maybe you'll be taking the food out with you, but at least you'll have something JUST IN CASE!
Pray for good weather!
