oldbloke's mutterings

Following McLaren's superlative performance today, I find I have page full of greens on BetFair, for both constructors' and drivers' championships. Yes, the lay offers I've had in for the best part of a fortnight finally got taken up, and now it doesn't matter what happens, I make money - or, to be strict, in the drivers', I can't lose.
Now, of course, Ferrari are priced longer than they should be (probably) so I really ought to back them... And maybe Raikkonen at 2.6... Obv, I'd also put in lay offers ready for when the market swings back.
