Great photos, I love Max's tongue hanging out.
Fun! Have you read the book "Potato People" by Pamela Allen? Might be a little young for your boys, but it's gorgeous.
Digging out all your own potatoes, wow that's really exciting. I love the picture of your puppy our Molly turns 1 tomorrow! I'm trying to grow vegies in my new patch but sadly nothing is flourishing much just yet, they're looking a bit spindly. I'll keep trying though:)
