"This week has been a lot more different than what I've thought all season," said Jarrett, who will start 37th in the Food City 500. "I've always been able to say, 'I've got a few more weeks,' or, 'I've got a couple of months before that comes.' It was easy to say at that time, but we're here. This is it this week. I've found myself thinking about a lot of the things that have happened over the last 20 years. It's been fun thinking about it, but kind of difficult to see now that it's coming to an end. It's been great. I've had a wonderful time."
