Over the weekend of April 18, Team Fox member William Russell and his fellow herd of enthusiastic, cow-costumed colleagues hosted the 5th Annual Cowfest in Vail, Colorado.

An udder-ly awesome weekend of skiing the famed resort town's slopes, Cowfest celebrates the season's closing weekend while raising funds and awareness for Team Fox.

With dozens of participants donning spotted costumes to hit the slopes this year, Cowfest 2014 raised nearly $3,000!

The motivation? William's mother-in-law and fellow Team Fox member Marian Bell, who has lived with Parkinson's for nearly 30 years. "As a wife, business owner and mother of five children, Marian didn't let Parkinson's slow her down.  She's kept her positive attitude, endless energy and has defied the odds by living life to the fullest, " explains William. "We remain hopeful that the important research being funded by The Michael J. Fox Foundation will soon result in a cure."  

Congratulations to William and his whole Cowfest 2014 team, we're grateful for your efforts and your contagious enthusiasm.
