1. let goodwilling freinds at home know about your situation, and arange a place to meet, and a signal. once you run away, send the signal and have them pick you up. doesnt get any easier. just make sure they dont drive directly to the school. may also be smart to use a different car for the pickup than for the drive home. get an automated licence plate cover, so you can cover the plates when need be.
2. be a program bitch untill the last second. you have to act very well. let yourself be taken over, allow your mind to be as pliable as play-doh but never, ever, ever forget who you really are. always maintain the ability to snap back to your old self. as said before, reistance breeds suspicion.
3. if you are in a rural or suburban setting, STAY AWAY FROM THE ROADS!!!!!! follow the road, but maintain good distance and cover so that no cars can see you, only use the road as a guide. put at least 20-40 miles between you and the school before you attempt hitchhiking. that much walking shouldnt be much for someone coming out of a wilderness program. change your appearance first!
4. never take rides from anyone over 30 unless you truly belive they will help you and wont ask questions. older people tend to not care and assume you're just a runaway. aim for college age kids.
5. try to cultivate a relationship with someone not affiliated with the school, but who lives around it. this will help greatly.
6. memorize all important phone, bank, ID, and creditcard numbers.
7. if possible, set up a bank account or safety deposit box in a local bank where it can be acsessed solely with a password or pin, no card or ID. put an extra set of clothes, an ID, money, etc in the box. most banks have this service although they do not advertise it. speak to the manager, you might have to send some money his way but you can most definitely make it happen.
