One of the perfect examples of what the experience of PAX is like comes from an encounter I had on the subway on the way to the show. A guy dressed as Nathan Drake stopped me to chat, turns out he is a random person I met while waiting in line at the first PAX East. We were really bored in that line and I had just bought some new dice so I asked the guys if they wanted to join an impromptu roleplay session. As we had no books I made up a scenario based roughly in the D&D 3.5 world and did a 45 minute session with four random strangers. This person on the subway told me that he remembers that and tells people about it as one of the coolest things he had ever experienced. It was one of the things that made his PAX experience that year and locked him and many of his friends in to the show from that point on.
PAX is not just a group of geeks and nerds gathering to talk about children's hobbies and act weird as some outside folks would lead you to believe. It is a community of strangers who reach out to each other with their common passions and ideals and become family.
