Thanks Kat! We are going to layer, layer, layer. I am bringing our big coats just in case, along with several light jackets. Oh, and mittens also for Aubrie, Dillon and I. Jer laughed at that idea but I don't like to be cold, so I WILL be prepared for the colder weather!! We are planning on renting a locker each day to put our coats and Aubrie's costumes if she wants to change.
