I am a solid #3 food packer. I suffer with low sugar problems so have to be very careful with foods that cause spiking and then the crash. There is always some peanut butter handy to power through the portages. Even the quick oatmeals slam me too hard so I stick will steel cut oats or multi grain cereals. I used to bike with a friend who believed sugar was a great fuel, the results were not pretty. That #3 thing is when I am solo. Some of my friends really like to eat well and that is fine by me. Especially when they come by floatplane after I have been in for a while. :P
