re: crumbs in my beard
My favourite snack to wear (on my shirt on my face on my lap) are homemade date squares. They basically consist of a date mixture shmushed between layers of crumbly oatmeal mixture. Yes they're as messy as they sound, and as good and not at all too sweet. But if you don't have chipmunks swarming your campsite you soon will.
Brad’s mention of date squares got me thinking about cookies. And bread.
I am a cookie monster, and my wife makes date nut squares. The inevitable crumblies are rodentia bait, and they fall apart in food barrel storage. For replenish on the road ubiquitously available in any grocery store I am fond of Fig Newtons. Fairly sturdy, and something about Fig Newtons prevents me from scarfing half the package at a sitting when I have the munchies.
For grocery store bread I prefer Rye or Pumpernickel, or sandwich rounds if I’m on a long trip and want the bread to last unmoldy for weeks.
No doubt chalk full of preservatives, but they hold up well in barrel abuse. And other experimental abuse.
