Aw, man, I can't imagine when I'd ever get to use a Cape Horn voice. The last time was more than a decade ago, working at a Renaissance Fair, when I had to be heard over the jousters and the kettle drums. Not even on those rare occasions when bellowing an order to the ranks, or shouting the next tune title over the snare drums.
Bloody hell. Now I'm mad because I'll never get to use my Cape Horn voice! *pouts*
You know, there has to be a difference between generic bellowing, and using a Cape Horn voice. I do bellow around my family--if only to be generally acknowledged amid all the obnoxiousity--but there has to be a difference between general family-style bellowment and Cape Horn voice.
