People are stopping and looking up to see something that people built go overhead, and people write me about that all the time and it's that ability now because of technology to directly connect to let people share in the experience as it happens, that I think makes it even richer than just looking and debriefing and showing a film afterwards and so I'm really happy when people send me a note back and say what one of my pictures or something that I've said has meant to them.
