Posted: Contact Permission: Only the person I am looking for and people offering free assistance may contact me. If you knew Pete and know of his current address, I'd appreciate it if you let me know how to reach him or let him know how he can contact me. If you have news but don't know his current address, would appreciate that, too. One friend passed away in 1979 and always thought I would get to see him again. Alas.

They wouldn't post this message elsewhere on the internet because it was the free, trial account, so posting it here should result in it being indexed by search engines.
