I want to fire a flare
Never did it before and thinking that learning in an emergency is not the best time.
Is their any protocol about how to do this without it looking like a real emergency?
Backyard is an option, the beach is an option but every place will attract some attention and on the boat is a better drill anyway.
A radio announcement maybe?
I've seen test firring recommend by several books but no one has addressed the practical problem of exactly the best procedure in a very urban environment.
