I enjoy carrying a moderately (or more) heavy pack, taking along some refreshment or treat for myself and/or my partners . . .
(1) "Moderate" to Laura = 50 pounds. I've never asked her what "heavy" means - not sure I want to know. I've seen her haul 65 pounds in July. For me, 30 pounds is when the cursing begins.
(2) "Refreshment" and "treat" are Moose-relative as well. For bottled Scotch, refer to (1) above.
