A HANS is certainly on my list, but just playing devil's advocate here.... is that a cornfield in Iowa?
That looks like some backyard dirt road vs the nicer tracks most of us round here are running or plan to run our cars on.
Another point to take is knowing the run off and and overall setup of the track you plan to run on. Greg always like to say that he likes Thunderhill because it is nice smooth well maintained track with sufficient and smooth runoff.
But, good post True, definitely something that should be on many shopping lists.
