How do you liven up a boring photo from a foggy morning practice session?  You cheat.  I had a friend "Photoshop" in the exhaust flame from a Turbo-Porsche (a variety of car well known for such things).  Mac's Cobra developed ignition problems and really was shooting out flames during his race later in the day. 

And a note about digital cameras.  I only had two batteries and four 512MB SD cards.  I was worried about filling up my last card on Sunday so I was checking a lot of my photos and deleting any that I didn't think merited card space.  This operation is very battery-intensive.

So I saved card space but my second battery went dead before Mac's race.  My first battery was recharging at the media center.  Because of poor power management I missed immortalizing Mac's three-foot jets of flame and had to resort to Photoshop cheating.
