I've seen news coverage of that field in Darfield and it's just like a
giant has torn each end of the field apart with half of it going one
way and the other end going in the opposite direction.
There are still new cracks and crevasses opening up each day as the

That might be something worth investigating.
After all, if it's true, that's not a good trend...

Same thing is true for kites. I have a couple that you tie off to the hitch on
