Damn! We live in Vancouver and passed through Whistler yesterday.
I can't find a Whistler "Stoney's" in Google. Is it still there? If so I might
try to stop in and stare down the 'tender while he makes one. It doesn't sound
all that good to me (I hate artificial grenadine) but I'd choke one down for
the joke.
Honestly though it just sounds like a Velvet Hammer with color and goofy
garnish.
