I don't really have a good answer why I didn't notice it, just a combination of things.
A crew looks after my yard, and I don't spend a whole lot of time back there. I haven't really noticed a wasp problem the few times I've spent any longer amount of time in the yard -- even when I've been out there to BBQ, no wasps harassing me.
The window I took the photo from is a spare room that has had the shutters closed for pretty much the whole summer to help keep my house cool. Plus the location of the nest was closer to my neighbour's deck than mine, which might be why he noticed it first.
And in hindsight, I still can't believe I didn't spot it: it was HUGE!
I asked the exterminator how long he thinks it'd been there, and he said either the first or third week in May (I forget).
