it's true, there is an expression (at least where i'm from) that if you can 'dig a hole to china'. turns out, if i had dug that much, i would have ended up in the indian ocean. how fun is this though? you can actually see where you would end up. i love it.
if you dig from ireland, you end up in new zealand. gerry said as a kid, they would 'dig a hole to australia'. turns out they were wrong too.
