Don't underestimate the value of a cool beer after a long route.
On long hot routes, a smaller frozen bottle of water is great, sometimes tied onto harness with cord, cheap, easy, reusable, disposable if needed.
Maryland choc biscuits, even when crumbs and stale after months in the pack. Always welcome.
Its all about food, isn't it?
