HAh! Luv it! And in my younger days when I was stationed in San Diego and my girlfriend was in San Jose (my hometown), I made that trip nearly every weekend. But I drove all night. Had to stick my head out the window most of the time to keep me awake. I think my record was SD to SJ in about 4:45 doing 90-95 most of the way. :)
Nothing like a little impromtu photo session to break up the monotony of driving down beautiful hiways with the sun roof open and the windows down and good jams on. Looks like you were enjoying the moment, and this is a fun shot.
