Fishing is not unethical, neither are campfires. Since I backpack in brown bear and wolf country I also carry a large bore handgun along with my fishing gear. How's that for politically incorrect? The only time I won't build a fire is in the dry season when the U.S. Forest Service prohibits it for obvious reasons.

I don't have much patience for the holier-than-thou types that look at gas-powered stoves, for instance, as being unethical since they use evil petro chemicals. Where do they think nylon comes from? How about gas for their sacred Subarus that transport them to the tralhead?
