By comparision to these guys it's true--Boomershoot is lame.  The largest Boomershoot targets are like 1/30000th of what these guys did.  Boomershoot has excellent neighbors but I just can't ask them put up with even 1/10000th of that event.  Orofino would probably complain about broken windows.  Man, that was awesome.

My calculation is that they were just under a mile away.

H/T to Ry.
