Mad River always kicks my butt, no matter the time of year or snow conditions.
The day in early March 2011 when me, my son, and Laurel Hill Crazie skied MRG we had a really fun time, but very challenging. More than once during the day I uttered the phrase, "I'm out of gas". It's a heck of a layout. At one point when we were skiing some of the easiest terrain I came upon a green circle run that had a stretch of well defined moguls the size of a football field. Couldn't remember ever seeing that on a green circle trail before. For those who don't know the place here's a link to some photos we took in March. The run under the single chair is Chute and it features big bumps and a number of cliff drops and stays tough for a full 2000 feet of vertical. Of course, much of the gladed terrain at MRG is even more challenging because it includes the same steeps and rocks, but with tree dodging thrown in.
