David had Michael talk to Aaron to get him relaxed.

Huge containers on the surface at CMS.

A few of the beryllium LHC beam pipe where it enters the LHCb experiment.

That is me being setup in front of the ALICE experiment. Photo taken by Erika.

For this shot David took out 5 flashes. One behind me to throw a ring of light on ALICE, two behind left and right with blue filter to throw some blue separation light, one small soft box feathering me from camera left and one ring flash as frontal fill. Photo taken by Erika.

"Yeah, look at that...". Photo taken by Erika.

"Nooo, you really did not got that shot did you...". Photo taken by Erika.
