Yea, wasn't really clear that I was joking. Not a whole lot of minivans out there on weekday afternoons I bet.
On a serious note, though... it would be cool to head out there with some FJs on a weekday or something when you are essentially guaranteed not to run into anybody. That way you could spend literally as much time as you'd like per obstacle to fail repeatedly, blow up, do time-consuming recoveries, etc.. and not have to worry about tying up the trail.
