Fresh manure

So we go out to my dad's new girlfriends house this weekend. Nothing like the smell of fresh manure. She has 4 horses and lots of droppings! The kids all rode horses, well Sky and Jay did. Josh sat on one for about as long as you can expect a 19 month old to sit on one, and then wanted off. I didn't ride although they tried to get me too. My dad told me the horses (other than the pony the kids sat on) are jumpers. Didn't want to break my back this weekend so I passed. So how did I get exercise? I chased Josh around the whole time making sure he didn't fall face first into a pile of fresh manure....
