Hold On!

Does anyone know who these folks are? Looks like they were having a blast. I was a little concerned that they might get washed off the rock at one point. I'd like to contact them and give them a copy of this image. I'm thinking a new facebook profile shot?

This was shot at UCSB Campus Point from the top of the bluff on Oct. 19, 2007.
1/640 sec at f/5.6, ISO 100, 300mm
