They've got a GPS riding along in the pilot car. If you want to follow them along the route, you can see the map here.
I've got to be up in 4 hours to get to the church by 3:30'ish for the rollout at 4 am, so I'd better hit a bed now.
If I can get online via someone's bluetooth tomorrow, I'll blog from the road. If not, you'll get tons more photos on Sunday.
