Well, Top isn't a big fan of stockcars. At least not while he's working. He'd go along pretty good, then one of the cars during their warmups would back fire... not good. This warranted dropping his butt and launching forward with his head up. When he'd connect with the line, he'd buck. We'd regroup, be working along pretty good...another backfire. Same reaction. I think maybe if the backfires were consistent in timing it wouldn't be so bad. It's just that they are so random. He gets no preparation, and they are always a surprise.
