Thanks
I kinda just rigged it on the fly with random stuff I had in my trunk.
some shots required the tripod to be affixed to the front headrest and sticking out of the window... another shot had the tripod sticking out of the rear window and one was mounted on the front windshield. The rear one did'nt come out too good because there was a lot of free play in the tripod because it was strapped to the towhook and another hook inside the trunk.
We just went to an empty parking lot and pushed the car in neutral at like 5 miles an hour if that. It was really difficult getting the angles I wanted, so next time I try again I'll have more supplies to pull this off better
