If you are going AWOL you would never take your car unless you want to be found before you barely have time to leave the county.
I think a lot of us think of different things when we think of AWOL. We have heard through the threads plenty of stories of guys going AWOL who just go home and either sit on the sofa for a year or maybe even find some cash-in-hand work. I think it's good for us all to have different perceptions of AWOL because they won't all be identical, so we should consider various 'types' of AWOL?
Corrie had an entire weekend (Saturday and Sunday) to drive that car with no one looking for him. So, say he wanted to go to some place several hundred miles away, then driving the car to Cambridge/London/Birmingham and then leaving it in a car park and getting on a train with the bag of clothes (after having changed clothes) could still make sense?
I also feel that the money is problematic. Even if Corrie had a friend's place to go to and they got supermarket deliveries...someone has to pay for this, and Corrie apparently has no clothes and a very healthy appetite and no money, and no bank withdrawls since he went missing. If Corrie has a friend about the same size, then they could loan him some clothes. They could maybe pick up some clothes from a charity shop. But it's still considerable expenses for the average person to do this kind of favour for a friend? If Corrie does have a friend doing this, then I can only hope that Corrie will get in touch with his family and let them know he's okay.
