I rode with Matt Entz in South Fork, Co this past March. It was my 2nd trip ever snowmobiling. My first trip was riding 2 days on a rental sled at Togwotee Mountain lodge. I purchased a new pro rmk 800 this past winter and took a friend of mine with me to ride with Matt. My friend had 20 years on a snowmobile and he said he learned more in two days than in 20 years. Matt was extremely down to earth. I was actually shocked at how humble he was. He stopped in South Fork and loaded up our sleds in his trailer to head to the pass. He swapped clutch weights for me and was happy to do so. He offered any of his avy packs and gear to try out. I was out of my element the entire time, but he was an amazing instructor. I still remember some of the tips he gave me like it was yesterday. Every time I was stuck, he was there immediately helping me or riding my sled to a better point to get started again. I haven't ridden with any of the other clinics and I have no desire to after riding with Matt. He may not be the biggest name out there, but his skill set is unreal. The amount of 1 on 1 attention was amazing and his patience with a novice like myself was unparalleled. South Fork is a long drive from Sioux City, IA, but Matt Entz will likely be the only person I give my hard-earned money to. I can't say enough about this man, his talent and his clinic. You should have no fears about signing up with Mountain Skillz.
