Worked my way in position at the finish line of the drag boat races, part of the annual thunderboat regatta in Mission Bay, San Diego. If you haven't seen these guys live, it's increadible. Zero to ~240 MPH on water in a qtr mile under 5 seconds. So loud they shake your gizzards when they blast by. The far boat exploded into flames about 100 yards before the finish. I clicked several frames on my 40D and was able to capture this close finish with the far boat in flames. I'm definitely going back next year.
