According to SC's Facebook page, the location for next year's SCI will be announced on Sunday. They are posting clues as to where the event will be held:
1) Hometown of a multiple Canadian champion (doesn't say male or female)
2) An Annual General Meeting was held there within the past 10 years.
I'm guessing Edmonton (and if it is, I'd better be seeing a whole lot of you there in MY stomping grounds!)...
