My husband and I are big Nascar fans -- especially the Sprint Cup. My husband knows and understands all the technical and mechanical stuff. I, on the other hand, do not.
I know the basics -- the pit crew looks after tires, fuel and adjustments to the cars, and they do it really fast. The cars race around the track counter clockwise, sometimes 3 and even 4 wide, which is really exciting. There's a pace car used for restarts after a caution. Everyone follows him at a slow pace until he leaves the track and heads into the pits. That's when you can HIT THE GAS (don't follow him into the pits)! There are spotters, crew chiefs and other people. That's about all I know detail-wise.
Yup, I may not know much, but I do know what I like and I like .... no.... love ...watching those cars go round and round for a couple hundred laps (or more). It's especially exciting when there are driver rivalries. Heehee! That makes for an exciting race!
The drivers -- I love cheering for my favorite drivers and cursing the rest. Such fun! I have 2 favorites: Mark Martin (last of the gentlemen drivers) and Tony Stewart ('Smoke', great sense of humor).
