Madison Magazine, July 2026


Illustration for Madison Magazine. “Why are there goats in Madison’s parks?”

There are 5 goats all different colours doing different things to clean up the park. They are all wearing blue tops and orange hi viz. One is using a leaf blower, one stands atop a mound of leaves with a big gardening fork, one in the middle is wielding shears, to the right is a white goat eating grass and there is a goat on the right with a weed whacker. The background is an amass of green foliage shooting up and around the page.
