those sorta pics are more exciting to look at, show the speed of the car .... these pics while they arent terrible by any means and they will sell (as shown) just dont do the cars justice .. the cars look parked, unmoving and boring
as for me coming to Zcon ... i'd love to and would've this year but had already planned a trip to vegas prior to zcon being announced so it was out of the question.
next year its in Daytona ... which is a trip and half for me .. if I go it would be w/o the Z, and I'd need to set stuff up with whatever track the event will be at ... then hope the track hasnt set up an official deal with a photographer that would keep me out of getting anythign decent.
but hey I'd love to, panning shots just do the cars more justice I couldnt see paying for shots like those just no excitement in them.. just run of the mill
