In 2010 I met two friends at Kearsarge Pass . . . and at that point the can was pretty empty, so your right . . . MTR to the Portal is a little to far for the 101, but I can fit about 5 or 6 days of food in the BB 101.
Typical day on the trail for me is an energy bar in the morning, another around 11 with some gatorade, a GU and another gatorade around 2, another bar in the late afternoon, then dinner. I'll mix a few other things in if I get hungry or feel low on energy, but I keep it pretty simple. I always have corn nuts and snickers too.
