Soooo ... it rained a little bit during the races this weekend...

On a side note, both of my cameras got soaked. The Rebel XTi is built like a tank. The 6D ... not so much. Started behaving erratically and I eventually retired it early to the trunk of my vehicle to dry off and will see in a day or two if it's back to normal or needs service. It kept on shooting just fine, but I was not able to review images, change settings including shutter speed, etc. I think water got into the back dial and the live view button area. Trying to review images started to turn on live view instead!
The XTi never flinched.
