I dont know what the hell that this is but it FREAKIN KICK-ASS!!!!!

it looks like its some sort of mining equipment.. but I have no idea.. on where and for what reason they need something that big new tunnel beneath the pacific or something ?

Looks like a trench digger.
Wonder how much it'd cost me to hire one of those for a day from the local equipment hire place

hehe.. maybe less than the transportation costs :are

I bet one of those in your front yard would keep the salesmen away.

I am also curious as to what exactly it's intended to be used for...
