I don't have kids, but I have borrowed some nieces to take apple and strawberry picking and it's fun seeing them destroy some delicious fruits!

I keep hoping vertical farming or hydroponics, etc will catch on and bring foods back closer to home. As long as we have sunny parts of the world with cheap land and labor, it won't be viable though as a business. Maybe in a few decades...

I've tried container gardening a bit, as I didn't have a yard, and while the results were meager due to my lack of farmer knowledge, they were still tasty. Can't beat peak picking time, no matter how small the result may be!
