Jesse;
The spot is just west of Kagel at the end of the range before it drops down to the Santa Susana Pass in Simi. It's Conservancy land and accessed through a locked gate by permit. Otherwise, you'd find me flying there often.
Joe, that commercial is fantastic. Very appealing. What amazing work. I think I know the exact spot. So fun to watch hang gliding on mainstream media filmed by my neighborhood (Santa Suzanna area) and by Joe. Sweet.
The setting is Oat Mountain above Granada Hills - Northridge and I believe Joe said the Emu was digital. Even Joe and Rich wouldn't fly tethered to each other these days but way back when...
