We were at the Grove. Walker had been faking low on each restart, then jumping back in line to clear the cone. On this restart, Walker again faked low, but Sammons (the # 747) ran out of fuel and pulled down and Walker had no where to go but below the cone. If he had been in line he could have cleared Sammons on the outside as the others did. Officials were going to penalize him 2 spots but Walker decided to race around and run over the cone and then pulled in. Up to this point I can see both sides. His actions afterwards on the front straight were ridiculous.
