It's after the fact, but this is a conversation I had on Twitter just now with the girl I had met at Mosaic. Turns out that when she was leaving, one of the teams had stopped to ask her directions to the Pitstop. I thought it would be interesting to see what was actually on the clue the teams received:
Steph: 7m
Hey! Weird question.Curiosity kills the cat.You seen the last 2 check in? _______ came last? So they were eliminated? Was it by much?
Corey:6m
I'm keeping that to myself

Lets just say it's an intense finish. Regina traffic and construction didn't fail to deliver on the suspense
Steph: 5m
Hahahaha I gave _______ directions. That's why I'm asking. Bahaha. But I'm glad it was close. Such a cool day!
Corey: 4m
Nice! Did the clue name the island or just say Wascana Lake?
Steph: 3m
Named the island in wascana park
Corey: 3m
Very cool!! I didn't even know that that island had a name. My friend that lives there called it "New Island". hahaha
Steph: 2m
Oh I know! If it didn't say in wascana park woulda been way more confusing. But I figured that's where it was
Corey: 53s
That's so cool! Looking forward to seeing you on TV! We'll know then if what you did changed the outcome!
