My wife is sorta interested in trying it, but when I suggest we actually do it, she seems to find a reason not too that day. That's ok though.
However, she goes with me to every contest I fly, including the long haul contests (20 hrs to Texas earlier this year, what a drive), and she is really supportive of all the time and money I spend on these things. (And sometimes, I think she is a more aggressive competitor than I am, which is pretty scary

)
She wants nothing to do with the noise, mess, and the smell of fuel just doesn't do her, so I don't think she will get "hooked" even if I do manage to get her on the buddy box a little.
