 Part of the reason for the extended caution here is some of the large decals that line the concrete barriers around the racetrack have begun to come apart when the cars have bounced off of these walls. We've heard Brad Keselowski and Shane Van Gisbergen talk about it. As a matter of fact, Shane Van Gisbergen mentioned that in our Progressive Keys to the Race earlier today on NASCAR Live Race Day. You have to get right up against these walls. And Brad Keselowski said it yesterday in a qualifying show, Jeff.
