Would that be Dave Redman? If so he would be the best choice as he has grown up around 4 wheeling with the Grass Valley 4 Wheelers and has done the Con many times.My buddy is a pilot for Sierra Air, and i know they would love take you over the Con for pics. When calling ask for Dave to take you up.
I flew with these guys in October. They'll take you over that way.There's a guy at the South Tahoe airport that does scenic rides around Tahoe.
