Long Beach Grand Prix ALMS BMW M3! Anyone going?

Hey everyone. I was in Long Beach today watching the ALMS practice run at 5:00pm. Watching and listening to the M3 racers was amazing! They are not as loud as the Ford GT40 or Corvettes(the loudest) but still a treat to your senses. I will be out of town this weekend and I hope some of you will be here and take better pictures or even videos.
