This is obviously a topic of extreme relevance for a lot of people, Rick. I'm glad you brought it up.
In fact, I saw a similar discussion on the SCCA boards a few weeks ago. One guy almost had me in tears. I mean it. Long story about a guy who involved his wife in his racing, bit by bit, but was never sure if she liked it, and even one episode where she was a passenger during a club race and got scared out of her wits by a near miss. This guy always felt guilty about that episode, and they never really talked about it. (Here's the tear-jerker). After she died of cancer, he was reading her diary. In it, near the end, she had written an account of that racing episode. For her, it had been a highlight of her relationship with her husband, and of her life.
The jist of all that was to a) try to get your wife involved a little. It's tough, I know, if they don't seem interested, but if they understand some of the stuff you're doing, they might be more interested. b) Have and show true interest in what they love to do. Do it with them, and without grumbling or whining. See it through their eyes. And give them the benefit of the doubt in helping them see through yours.
Bleed your brakes often, and whatever you do, don't buy speed bleeders.
