Circle the wagons

I just got a phone call from my mother. She and my dad are on a tour of England. She was calling from the hospital - my dad had a stroke. He's on a ventilator, and not responding. I don't even have a passport, so I can't just go over there. My brother does have one, so he is on his way later tonight, but still won't get there for over a day. I hardly know what to do with myself. So positive thoughts and prayers if you are so inclined. I'll post more when I can.
