I just wanted to thank you so much for sharing your ordeal, with all it's frustrations, as well as victories, with all of us. I'm a grandma, who has spent the first 5 years of my retirement taking care of my, then, youngest (and 9th) granddaughter while her Momma worked. So, it was with great admiration that I followed your story and your gift for sharing with the kiddies, and their enjoyment and excitement in the progress. Congratulations on your success, and on your VERY impressive gift of creativity and ingenuity. I had been thinking of trying to DIY something along those lines, but never got very far with it. Your water change barrel is just genious. Awesome.
