As you get older you might like to reconnect with some of your high school classmates. One way to do this is to utilize a free people search and plug in their name to see where they are. One of the tools to help you with locating your long lost friend is through a Yahoo people search on the internet.
You can type in that person's name in quotes and see what happens. Usually if a person is well known, or active in his or her community, something about him or her will pop up on the internet through the Yahoo people search engine. What you'll find could be something about what that person had done recently. Perhaps they volunteer for the humane society, and helps to save stray cats in the neighborhood. A reporter could've interviewed them regarding their community service, the story was later published, and it's still available online.
This information will probably tell you what city they now live in and, perhaps, a phone number of the organization where they volunteer.
