I came up on a musher on an unplowed FR today & was unsure how to pass? It took a while for the musher to stop be she did stop tried to set a brake then just turned the sled on it's side. I just stayed put not sure what the dogs would do & good thing I did because the lead dogs veered left on the harness right where I would have passed. I kept waiting & the musher pulled the dogs to the right & waved me to pass. Pretty blond girl not what I would expect in a musher & she handled the dogs very well. Something new every day in this sport & the mushing looked like alot of fun & I would luv to try it.
