So, I searched his name, which is very unique (and by that, I mean his last name). I found out that he has a Facebook account. I don't have a Facebook account, but from what it could show me was his picture and his location. His picture showed it was obviously him...
(IMAGE DELETED)
and his location showed a small city in Illinois, which is where Camp Bunn was.Thanks to some good work by my dad, we found out he had a Steam account. Thanks to us goofing off a little at camp, I found that he had Steam games (Portal, Left 4 Dead, etc.), so it made sense. Unfortunately, he had to be my friend to send him a message, and he disabled being able to leave comments on his profile. And begin inactive for the past 2 weeks didn't help either. But, there was still some small light of hope.
I searched up his username and found that it too was unique. The only places I could find his username were on technology-related sites, so I knew it was probably him. However, in each of his profiles, he didn't give away any of his personal information. (Good for him.) The only way I could find his email address with my information was to pay some money to some service, which I was not doing.
Or, I could just email the camp director Miss Lisa, whose email was provided on the Camp Bunn website, and ask her for Pete's email.
So sure, I didn't get as far as I planned, but think about how close I got, and how easy it was to get the information. Plus, if I just continued to refresh his Facebook page, I could probably see all his friends. But then again, I did have some previous experience with this guy, so I knew what he looked like, what his interests were, and where he lived. But, still...
UPDATE: She has e-mailed me back, and said she'd be happy to help. Yay!
