This is from my D90, with a Tokina wide angle lens, on a tripod on the back seat of the car with 2 legs locked in with seat belts and the other wedged on the centre console :-)
I used a release cable with a timer to trigger the shot.
I live in the city and the only reason I bought a car was so I could go more places with my camera. Expensive camera accessory really.
