He called this morning but I haven't talked to him again since. The chaperones decided to take turns taking hour-long breaks and going back to the dorms for some rest. When I talked to him this morning he was heading back to the dorm for a nap.
Andrew, A.J. and I went out to dinner with a friend of mine tonight and Matthew called home and left two messages on the machine and DH left one. And I missed a call on my cell phone. Hopefully they'll call when they go to the dorm which should be around 11:00 our time.
