You have been very busy, at the races. Great shots of MotoGP, Formula 1 and vintage race cars. The damp track shot of the Moto3 rider, with a single tire track, is a great capture. I really like the tight shot of the Indy car. If I remember correctly, that was the car Tom Sneva drove in the Indy Car series. Many great panning shots in your series. My wife and I are going to the MotoGP race in Austin, Texas in April. Hoping to have some shots to share.
Thanks very much Geoff! I believe you are correct about the original driver of the March being Tom Sneva. I'd love to do a race at CoTA - so many options to shoot backgrounds and especially some shots from the tower. Canon had an exhibition of Darren Heath's F1 photography here that I wish I'd seen before the race - great use of light and colour with very high and really slow shutter speeds. He has some great images of CoTA too.
