Throughout the month of January, all of Utah's ski resorts are offering amazing deals to first time skiers, including lessons. For a $13 lift ticket, $13 rental, & $13 lesson, you can ski Snowbird, the Canyons, and more. Pretty amazing stuff. I am hoping that the 4 lesson package at Alta will work for telemark lessons. Most are for Utah residents only. Go here to check it out. Alta's package is for kids too (4 and up).
P.S. The boys remarked as well, it doesn't look like they are going that fast, but trust me, when you follow them and see their little legs splaying to keep the ski together at what seems like was too fast (I am constantly yelling "big turn" to slow them down), they are definitely going faster than it seems.
