How about an "almost" dry run for the other person?
I delivered a pinball from Austin, Tx to Harlingen, Tx (about 5.5 hours one way). We called the lady the day before to confirm, and everything was good. I had a buddy ride along to help with the driving, as we planned to be there by 9am.
We left at 2:30am and headed down. Driving thru the night (no traffic), we got there way early (like 7am), so we went looking for a place for breakfast. Finally found a place that wasn't a 'taqueria', and killed some time. Finally get close to our scheduled time and we head over to her house - and she's not home!
We call the number we were given, and can hear the phone ringing inside. Her little dog is yapping at us through the window. We call back to Austin and make my boss head to the office early (we normally open at 10) to find another phone number. He gets a cell number and get the voice mail. He leaves a message, gives us the cell number, and tells us to wait for a while. We fall asleep in the truck.
About two hours later we're still waiting. The cell phone battery is dying, so we go looking for (and find) a Radio Shack to buy a car charger. While we're doing that, we get a call from my boss saying the lady just called and was on her way home. Apparently, even though we talked to her yesterday, she woke up this morning and completely forgot we were coming, so she went shopping.

Of course, she left her phone in her car.
Finally got the game inside and set up, played a few games to make sure it was okay, and headed home. Hit a lot of traffic on the way back (including one border patrol checkpoint) and hit Austin about 7pm...
