One of the favorite activities at my parents farm is hot rodding on the mule. The M.U.L.E. Aka a small all purpose cart has a top speed of 10 or 15 miles per hour. My kids grew up driving this cart years before they could legally drive. It was always the highlight of their visits. In one memorable incident, one of them (name unsaid), knocked over a tree and got banned from driving for at least that trip. And of course the shame has never left, her sisters or dad will never let her forget. Anyway, Mary has been up visiting with me. And egged on by her grand-daughters (remotely), she tried the Mule. Did well at that after learning to just drive over branches and through mud holes. Did pretty good for a first-timer.
