I usually ski alone, for between 4-5 hours at a time with no lunch or bathroom breaks. When I take my skis off, I'm done for the day. I'll ski anything from greens to blacks as long as it's groomed. Steepness doesn't bother me but rocks, unexpected bumps and sheets of ice approaching the size of football fields do. Breakfast on the drive up usually consists of Subway (12-inch egg white & cheese on flatbread with veggies), and the drive home sometimes includes the VERY minor/responsible consumption of an adult beverage.
