Just so that you guys dont get confused, sprint car racing is where you get dune buggies configured w/ material to make it look like an 80's version of a cartoon series show & all they do is run round a small dirt track. Think redneck version of nascar (even tho some rednecks do watch nascar) but not as expensive to watch as nascar. Sprint car racing is almost never televised (unless its a local newscast station that has absolutely no news to report). For more information in the SCR series, go to http://www.ascsracing.com/.
Might as well answer your question while im @ it. Yes I have heard of this, but never have heard it called that before (maybe cause noone has ever said it before).
