Local mule legend

A mule named horse and a dentist named Wolfe.
Missoula Mule named Horse was 23 years old when he passed, shortly after his owner and local dentist, passed. Their friendship was the cornerstone of the mule world and why ranchers and famers alike have formed strong bonds with their mules. While fightin Lou Gherig's disease local Missoula man Deloit was involved with many local charities, events and athletics. He worked on his families wheat farm in Kansas while going to dental school. He was on the Missoula County Planning board and other development projects later in his life, showing his love for his community but those close to him knew of his love for his "Horse" the mule. The mule who was considered "too hard to handle" in Kansas was eventually the 2008 winner of the Master's Horse Show in Calgary. Taking "Horse" into the Bob Marshall Wilderness was one of both of their favorite activities. Mules, like their owners, are stubborn to the end! And what an end the two had, passing just days apart. There is no love like that of a mule.
