First time at the track, very nice track overall, conditions were mediocre (drizzling, then misty, then clear, then foggy, then misty, then clear, then drizzling again).

If you want sound, you'll have to crank the volume to the max, my apologies. GoPro HD Hero is not the best in terms of sound quality.
