Took a77 and 70-200mm to Drag Races

Here's some of the video some wanted to see. But i need to preface that I don't think this video is a good indication of this camera's capabilities. I should have used a monopod if i was serious about taking good video, but I was sitting in the stands and the person in front of me has their back in my crotch and my back's in the guy's behind me's crotch and the girl in front of me keeps spilling her margarita on my Domke messenger bag, etc... So what you get is me hand holding a 70-200mm fat ass a77 without the vertical grip (which I removed so I wouldn't look all techy - not the huge white lens barrel wouldn't do that - sometimes I don't think these things through).

I tried to make use of the focus hold button as much as I could when people walked in front of me.
