I had great success just with facebook. I moved from NJ 38 years ago and reconnected with 13 friends from the old neighborhood. They're spread out all over the U.S. But one entire family that lived across the street from me has been living 30 minutes from where I am now for the last 20 years. Got together with one of those family members 2 weeks ago and it was great talking about old times and catching up.
Finally things have started clicking for me, my knees, my elbows, my back, etc...
