Let's visit the wayback machine...(cue Wayne's World-ish "diddly-doop, diddly-doop" sound and the screen wobbles into a flashback...)

HO's "Not if, but when on $80 oil" (and that's without a hurricane, eh?)
JDH's "$100 a barrel--what are the odds?"
Boone Pickens' Oil at $75 by the end of 2005.
John Robb's "$100 Oil?" (if you haven't read JR's front page lately, do so.)
Ali Bakhtiari's prediction of >$50/bbl at ASPO over three years ago. (my favorite quote from this one: "If there was nothing to be worried about, then there would be no price increases," explains Bakhtiari.)
Goldman's super-spike (courtesy of our friends at Energy Bulletin).
Matt Simmons calling the true value of oil at $182/bbl or that oil could be $100 in six months (ok, so he was a little off on that one).

Anyone else have any nominations for the wayback machine? Link and discuss some of the other valuations/price predictions out there.
