Face-to-face meetings with people you know from the Internet?

I've been close to visiting people I knew from the internet before but never really ended up doing it. I was usually with my family and it would have been weird. Although, I was playing GRAW on the 360 with my friend and using Live. After about two hours we enter this really specific custom game and start talking to the guy hosting it. After talking to him for a bit he asks us were we are from and we say Colorado. Wow what a coincidence, he is also from Colorado. He asks us what city. We reply Boulder, and he says Boulder. We ask him what street he lives on and he says a location 1 block away. We ask which building and which SIDE of the building. It turns out we can fucking see him in his window because he lives across the parking lot from where we were.

Eerie. Does Xbox Live let you join servers sorted by ping? If so, clearly you'd get a lower ping if the host lives in the same city, but it's still very weird.
