Help with racing photos

I guess I don't mind that these were shot on film. I've thought about doing it myself at times. Anyway, I like the second one better. Since there is not much else in the photos other than the karts and drivers, I think tilting the photo adds a little more to catch your interest. I would try getting some more of the background to catch more of the story, assuming the background is interesting. Just some ideas to try...

Off the subject, where is Ham Lake, MN??? I am originally from Southern MN, near Blue Earth, but never heard of Ham Lake.

Ham Lake is a 25 miles NE of Minneapolis.

That would work. (Or wait for a brighter day.)
Just use enough to keep the 2nd car sharp. A bit of blur in the background adds to the sense of speed.
