Yes, the shot in #10 is good. Yeah...the background is a bit distracting, in a way--but, 40,50 years down the road, that "antique" SUV and white horse trailer will look very of this era...and...you know, there's not a damned thing you can do about stuff like that at many,many event areas that I have been to: participants are often parked very near the competition areas at many smaller events at fairgrounds and expo centers. To throw the backdrop out takes a close shooting position, and a 300/2.8 or something like that; once you move back far enough to get something as big as a jump, and a horse and rider in all the way in a horizontal frame, even at f/2.8 the background will be recognizable, to a degree. But again--the historical perspective...some day that big gas-guzzling SUV will look like a 1930's Ford truck looks today--really cool, and "of a bygone era".
