Just watching ESPN2 covering some time trials for Indy and noticed the lawn (do this a lot with NASCAR, etc.) and its stripes. THEY are WAVEY??? Some are straight and perfect, some were even angled and straight, but some around the curves were wavey. Like the mower man was drunk for the first pass, then just followed his wavey stripes. Looks different. Very intentional I'm sure. Is there a reason?
