Here I am wading through traffic. Michael Ritch in the 28 used the top groove exclusively for much of the race. I tried the high groove but my car didnt like it. The further up the track I went, the worse the car turned. The bottom groove was the best for me. Another observation here, the 06 of Bobby Gill surprised me. He wasn't very fast and seemingly struggled all day. I was expecting him to be very strong. He usually excels at the faster tracks on the circuit.
