Join a local EAA chapter.
Many have flyouts for breakfast/lunch/dinner/local flyins.
Pilots who both own and rent usually have empty seats.
Ask around who is going and who has a seat(s) available.
The chapter I am a member of has a standing flyout for lunch the third
Saturday of each month, weather permitting. We have a signup page on our
website. Some signup in advance, others just show up at the appointed time.
We have taken as many as twelve airplanes and 22 people on some of our
excursions. It gets real interesting at the small towered airports with
a restaurant. So many airplanes arriving at the same time can overwhelm
the normally laid back tower controller.

However, in my youth, I thought flying was totally cool - yet
completely out of my domain. I lived in a very rural area
and we didn't have much money as a family.

I really wish I had been exposed to it earlier.
In fact, I wish I would have made a career out of it.

My wife is a little "weary" of flying, having the "nervous wife/mom"
syndrome.

I'd like to introduce aviation (not just flying) to my son
over time.

I'm wondering if anyone has resources or recommendations of how
to do this effectively without being overbearing, being realistic,
but creating true excitement.
I mean, I have some idea, but still, input and perspective from
other sources can be invaluable!

Are there books covering such methods?

Thanks to all in advance!
