Gisborne - a disappointment

We stopped in Gisborne because it is the most easterly town in the world! The plan was to be the first people in the world (except for a few on remote islands and they were probably sensible enough to stay in bed) to see the sunrise for that day. You can't keep going east since you hit the international date line and suddenly it becomes tomorrow, or is it yestersay, but certainly not today! However we didn't take account of the weather and although two of us were up, on the beach and gazing at the horizon at the time the sun was due to rise (6.15) all we saw was a vague glow, no splendid glowing orb.
The best laid plans...
