With the engine left running I jumped out to snap a fall photo only to return to find the driver’s door jammed. To my consternation it was not shut completely and wouldn’t shut nor could it be re-opened. Luckily, a nearby road survey crew had the smarts to retrieve an odd branch from the wood and fashion a pole which they fished through the small gap in the partially open sunroof. Poking and prodding they managed to depress a window switch and I was saved. Turns out that my shoulder harness seat belt buckle had flopped into the door jam on exit and fouled the latch. A perfect snafu.
