I've got an old super-8 movie, up in the attic somewhere, driving home from a hippie wedding in a park to my place, looking over a huge Corvette c.a.i. hood, on Orange Sunshine.
Driving (steering & shifting) while one eye is looking through the camera ruins depth perception. Maybe that's why when I pulled into the parking space I bumped the fence. Not hard, just a tap, but the eye that was against the viewfinder hurt like hell.
