Great analysis of how NASCAR is trying to expand it's audience. It covers the challenges (lots o' confederate flags at the races) and the opportunities.
There is also a heartbreaking account of the only black man to win a NASCAR race and how he wasn't able to publicly accept his trophy due to fear of a riot.
Wendell Scott beat the field in a 200-mile race in 1963, but as the story goes, NASCAR officials were worried about how the predominantly white crowd in Jacksonville might react to seeing a black man hoist the winner's trophy.
Buck Baker was declared the winner, and only after two hours of review - with the crowd long gone - was a "scoring error" detected and Scott named the official winner.
As a NASCAR fan, I am always looking for good racing. I don't care who does it.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
