Here are some more photos from a gentleman named Andy at event #3. After talking to him for a bit, he offered to send me the pictures and asked me to share them with the group. This is what he said:
I had a blast taking photos of the racers this Sunday. I took over 2100 images, edited that down to over 300 your towards the end on your go kart. You look like you had some fun out there.
Feel free to share this link with your racing buddies. In fact, please share this link with them. Should you ever need a photographer to capture some cool action shots, give me a shout.
