Welcome from the next state over. My kids (4) have all ridden with me and love it. But my wife never has. I have never pressured her. I upgraded to an Electra Glide this year but she still has no interest. Two years ago I bought her a fairly cheap Honda Shadow 750 from a guy near your neck of the woods (about 3 hours away from me in Iowa) and she has ridden it a handful of times with a learner's permit, but still has yet to take the MSF class.
But I look at it as a mixed blessing. When I go riding I like to ride, ride, ride, pee, ride, ride, ride, eat, ride, ride, <repeat>
Whenever I've gone with a group of people that include wives or gfs we sure seem to stop a lot more to do shopping :-)
But I know a lot of guys enjoy riding with their wives/gfs on back and I probably would too. But each style of riding has its pros and cons.
