I for one could care less if my wife is interested in rc planes. She can do as she wishes. Sometimes she DOES come to the field with me, but those times she would rather play with the dog than listen to me go on about the infinite details that is our hobby. However, I suppose it's the kid in me...but I like "showing off" for her when she IS there. And when she notices how I'm flying and says "I saw your knife edge!" That makes me feel pretty good, cause I know she really doesn't care that much for it, but she shows an interest in me, and she likes to see me happy. So I am lucky too.
I'm taking the wife and kids to Muncie for the Nats in July. I was surprised that my wife wanted to go. Sometimes you get lucky!
Have a good trip, and ENJOY your time with your family...AND the Nats!
