Certainly a case to be made at this point in time for no flash. Wow Chaucer! Looking at your books I'd strongly recommend " Washington's crossing By David Hackett Fischer. You can't put it down! Like Rosemary's Baby! Driving though New Jersey will never be the same! Mark William Rabiner As does the 6400 iso stuff.
