Looks to me as though KatiRoo was closest in post #33 at Sept. 24.
You are correct, I missed the date of Roo’s guess.
So what’s the prize? A shiny loonie?
Prize? A TronnaDope! 
(All sorts of things happen when I’m not paying attention…)
I think I’ve got to hand it to Seven who [del]guessed[/del] predicted Sept 17 back in July. He was off by a couple of days, but he was looking forward by 2 months. Even 2 days ago, I would have put the date forward by a couple of weeks.
Well done to the OP.
Now, who was the economist who predicted this last year, and was soundly poo-pooed? I’d like to know his feelings for the next year…
Unless I missed someone, the guesses were as follows:
rivulus - Aug 8-15 2007
Diceman - Aug 12 2007
Barbarian / amarinth - Aug 22 2007
Spoons - Sept 1 2007
ShibbOleth - Sept 5 2007
Dante - Sept 10 2007
Seven - Sept 17 2007
PARITY Sept 20 2007
KatiRoo - Sept 24 2007
panache45 - Oct 1 2007
Sunspace - Nov 10 2007
Raygun99 - Feb 29 2008
adam yax - Mar 7 2008
Rysto - Mar 14 2007
Swallowed My Cellphone - second quarter in 2008
Full Metal Lotus - Never
KatiRoo takes it at 4 days away from parity.
KatiRoo - I’ll send you a Canadian Loonie as the prize. Email me at “seven AT sevengraylands.com” with your mailing information.
This was fun.
What next? I guess a trip south for real estate ventures and American women.
New Democratic MPs in Quebec! The Canadian dollar at par! Dogs and cats living together!
If Roo hangs on to it for a bit he/she will be able to sell it for a profit! 
See what happens when we legalise gay marriage? Imagine if we’d legalised marijuana!
She received it for free, dear. Selling it for a penny gives her a profit.
Sorry, just thought I’d undermine the joke…
Wow - Even I didn’t think it would happen that fast - although
maybe you really can’t go wrong overestimating the weakness of the US $
I don’t think a loonie will do me much good here in the US (unless I can get a couple thousand more so I can relocate to Calgary), so
please donate the pelf to your favorite hockey team
Canadian, of course
