Re: Fishing etiquette! Do people have any?
On an uncrowded stream or lake if someone crowds me I walk away. If I find myself working in another angler's direction, I go around...way around.
On a stream or lake where anglers are "spaced out" (no, not like that...) I try to talk with people, asking if I'm disturbing them...and I walk away a lot.
I came close to hooking a child on a back cast once and that lesson stayed with me. I'm whipping a dangerous article in the air and have a responsibility to be careful...so I make sure it's safe to fish before starting up.
The idea of putting a fly in the air near someone on purpose sounds like assualt to me.
