Thanks all for some great suggestions. Never undersetimate the wife. She's too bike savvy unfortunately to try the " I bought that 6 years ago and just been waiting to build it " type excuses. The frame is coming to my home address so the oportunity to intercept and stash is pretty non existent.
I wasgoodonce...that's my normal posture, she wouldn't be able to tell the difference. Yes the marigolds and KY gags have already been cracked as I become a target for zealous airport staff from now on.
Ed, thanks for the offer but I can't fling it in the boot and drive over. As for the price - no I didn't pay anything like that

, and yes, they reallt had a reason for that price I'm sure...err I don't think so.
Hopping around the house with it under my arm could turn it in to the most expensive anti fall device if it goes wrong. It's a bit too inconspicuous to stash anywhere I can actually get to at the moment
TSC, I like it, but I'll still get slapped.
Reanimation - I played the discount card on the Foes, there are only so many jokers in the pack.
CAS, I'm running at 12 bikes at the moment, I think she's got me on grounds of reasonableness and relative numbers.
DBMTB - I think you've hit the nail on the head. The problem is I can't even run away from her at the moment.
Andy, it was a bit of an impulse purchase so I didn't check it out in advance. I just really like the way it looks...I would have preferred the green one but you can't have everything. I'm happy on a 1.9 rear though so I think I'll be OK. I need to sort out the build though. Still thinging about that.
