Thanks everyone.
theOmni, I'm lucky in the sense that my wife is very cool, loves cars, car shows and racing. We watch F1 on TV together, go to cars shows together and go to Sebring, 24hrs of Daytona and Road Atlanta together.
... and No, she's not just a tag-a-long, she goes to the pits, meets the drivers, walks around and takes pictures, shops for cool car stuff, etc... with or without me... it's great! Above of all this, she bakes an awesome cookie...
