Wow -- A Truck-Mounted Big Rig in the Bakken

"David" posted this; again, a great post.

A truck-mounted big rig seems to me to be a big deal, but maybe I'm just biased.

    A company web-site picture of the rig clearly shows it is not "truck mounted". On David's post, most of rig is hidden behind the hill in the foreground.
    Truck mounted rigs typically drill to less than
    about 3000 feet. Trinidad 221 is capable of 17,000 feet.
