Smoking the Hills

I watched a film (ok, so it was only a single scene) where a group of young men hike up to the top of a hill whereupon one of them pulls out a bong that he then fills with weed and smokes. And I'm thinking, who on Earth would destroy the natural high that you have just generated (through all that hard work) in getting to the top of that hill in the first place? You don't hike to the tops of hills to smoke weed. You hike to the tops of hills to smoke the hills!
