Thanks PRR GG1. Races are the perfect place to hone one's panning skills. Now I have to try to do a pan of a CSX train at track speed.
I've been to a lot of races & those GTI's have been the only ones I've aimed a lens at, they were not common. Sure thought they were neat cars. At the time I was driving a MINI. Little did I know in four years I'd sell my MINI & buy my own GTI.
