At 12:35AM PST (8:35AM GMT) on 1/24/08, the Warhorse Hoofprint was at G-9 of Caedarva Mire via the Dvucca Isle staging point (the second map of Caedarva Mire on ffxi-atlas.com). It was at the very east side of the G-9 square, just south of middle. I hope this helps!
Also, if people post in this thread the updated locations of the hoofprint as they come across it, I'm sure it would be appreciated. =)
Thanks,
Rowan
