Wow papa first your kids are beautiful. You know its actually such an amazing thing now days if you think about it for kids to be able to experience nature like this. I don't think you can put a monetary value to that. My brother-in-law was a head master and he found he didnt have enough time to spend with his own kids. He decided to sell his house and he went homesteading effectively. It lasted about 2 years and unfortunately it didnt work out for him but he never regreted a single moment of it. He said that time he had with his children and seeing the joy on their faces working with the animals etc was worth it. So I am so glad you are doing the same! Best of luck.
