Digglers. These are the contraptions you rent at Copper Mountain. They are part scooter, part bike. The idea is you ride the ski lift up and diggler down. This sounds like great fun if you have no fear of a total loss of control. Needless to say I am the only wimp in my family and I opted out. Last year I made the painful mistake of walking directly under the lift all the way down the mountain. OUCHIE! This year I took the green "Easy Road" and traversed down the mountain. This got me to the bottom about an hour after my family...so much later that Gregg made a return trip up to find me. I would have loved to have been a team player on the one hand, but I greatly enjoyed my pink iPod while soaking in the great outdoors.
