Thank you for the response, and the CC!
RTHKI- You are correct. Shot from the inside of the carousel. Been to Mid-O three times, and this was my first time shooting (or spectating, for that matter) from there. Wish I would have found it before, as the basically 180 degree sweep offers plenty of opportunities.
RedWingNut- That "thing" in the lower right hand corner is the end of those four short signs that look like concrete barricades. I actually cropped out what I could, but that was what still remained. I kept trying to get all the shots in before they got to that point, then just after they were out of view is where that little bump is. I know their right front wheels were coming off the ground going over it, but the grass was high enough to where it didn't really show up.
Mansland- Thank you for the compliment. Shooting race cars is like golf...just one decent shot is enough to bring you back.
