Yay for house husbands! I am a housewife, so there you are. We know the work involved. :-)
You have many choices. London is not a bad place at all to end up. Fantastic state of the art hospitals and an excellent university. I hope you have a good trip! August will be H-O-T. Get ready for it. People miscalculate how warm it gets here.
Are you looking for a larger city then? What kind of home/lifestyle would you like ideally? Scenery, activieties, etc?
PS. I use to live in Fergus-so it was cool when you mentioned it.
