Her main hobbies are gardening and knitting. She can't just sit and watch a movie or TV, she has some knitting projects going on, in her had as she watches. On our recent trip to Arkansas, she brought he knitting along and made two hats for friends in the time we were waiting in the car for the group, or in spare time at the hotel. Never while moving.
The stuff around the koi pond is for large birds. We had a great blue Heron back there a few times and it snacked on a few hundred bucks worth of fish. The posts are just copper grounding rods, that I drilled a horizontal hole in near the top. Then a long line of fishing line, in a star pattern. It seems to work, as the birds see the lines and supposed to be startled or afraid their wings will get tangled in it. The Japanese use it in their koi ponds is what she heard. I just sourced the copper rods, drilled the holes and helped string it up. She is out there measuring the salt level in the water to keep it high enough to reduce the algae, and not too high to hurt the fish. We top it off with the well water so no chlorine.
When I go off to track days she never asks what it costs, and I never mention it. I do not do any racing, just have fun on the track, and passing is allowed only on the straights and with the driver getting passed doing a point by to tell the faster car what side to pass on. With an old analog 200 HP street car I get passed a lot by the modern cars with 500+ HP and computers doing the real car control. I have just as much fun.

This is Charlotte Superspeedway. Me at 5,200+RPM in 5th. My great claim to fame is I passed a real 911 GT2 on track. I will admit it was driven by the guys wife, and her main goal was to not crash. But I did manage a pass!
