You betcha.
When I owned a 172, my wife would fly with me regularly. She figured that even a 100mile/100 $ hamburger run was better than sitting around the house.
One day, as we're driving out to the hangar, she says, "How come some of those hangars have 2nd-story windows and balconies on them?" I tell her how some people live in their hangars. After a few secs, she thoughtfully says, "Why don't we sell *our* house and buy one of those?" What a keeper.
Then there was the time when, turning crosswind, the engine decides to take a vacation. At least, that was the first 0.10 sec worth of thought (turns out was a stuck valve). Even after that (my first engine issue), she continued to fly with me. She *did* make sure that I test-flew it a few times after it was fixed, though.
Lastly, when we decided to build our Sonex, we went to the builders workshop in Oshkosh on Super Bowl weekend (as in, February). As we're driving on the snow-packed streets back to our hotel after the first day, she turns to me and says, "How about if I go with you this year?" Exact quote. I knew, however, that she meant AirVenture. After recovering from a sideways slide induced by my head snapping around to look at her to see who was sitting next to me, and what did they do with my wife, she mentioned how during the workshop she had been chatting it up with the other women who were not the primary builders, and they each gave stories about how they passed the time when the men were drooling on airplanes.
So she went with me. After the first day, she made me extend our dorm reservations for the following year. Her dad worked for Braniff in '40-'41, so her entire life was spent listening to stories about the DC-3. She was in hog-heaven at AirVenture. 2011 will be her 4th year, and we now go for 9 days. I'm out the door at 7:30 for forums, etc.; she sleeps in late, takes her time, and hits up the museum, warbirds, and antique aircraft. She's flown on the Tri-Motor by herself as well as the chopper tour. Sometimes, I don't see her all day until we meet at the bus park to head back to the dorms.
I'm blessed. Oh, BTW; #1 son is an air traffic controller, and #2 son is a CFI/I. It's really great when we all get together and she can converse with the men-folk, completely understanding the aviation discussions.
