The summit was cool my girlfriend has the entire q&a on video will try to upload once I make it back home. They soundchecked a few songs but we didn't get an acoustic performance of the messenger like they did in London. It was cool to see to take the band take the time to meet and greet every single person at the summit. If I had to guess I would say there was somewhere around 300 people there. I was able to get a thousand suns world tour poster signed by the band that's limited to 1000 pieces apparently(will upload pics when I finally make it back home my flight to ny was cancelled and now I'm waiting). Overall the summit was a great experience and I'm glad I was able to be there. Show highlights for me were Faint, Bleed it out with A Place For My Head over the bridge, and catching Dave's wristband!!!
