Back in the good old days...there were herds of Wooly Tufted Mammoths along the roads. You could stop at any time ...get some tufts...and do your testing. Now...you don't see so many.
Back in reality...I don't think you'll see a lot of gain unless you get past the buffeting...and then you are too close for comfort.
