Growing Potato in Compost Pile

I found a potato has been growing from my compost pile.
Should I harvest some potatoes this summer?
My compost pile has been maturing with rich dark soil and many earthworms.
It’s so relaxing to smell very earthy soil from the compost pile.
No bad odder at all.
When I keep kitchen garbage in the kitchen or garage for a while, they start to smell bad. But once I mix them with soil in the compose pile, they don’t smell bad at all. No flies flying around, either.
Is this because I live in a very dry climate?
My simple big hole compost pile has been a success.
