"Spousing" a work trip is awesome. Mrs mjohnson had an actinide chemistry conference in Tours, FR - kiddo (20 months at the time) and I tagged along. "Bye mum! We'll be at some castles and the brasserie". The next week was to some electron-welder-maker in Munich... "Bye mum! We'll be a the Augustiner".
I'm trying to steer mrs mjohnson into some sort of official business at a naval base north of Glasgow this summer. Or maybe Cape Canaveral/Kennedy. Just please, no, not ever again Amarillo (the charm does wear off of even as charming a place as that...)
Of course, mrs mjohnson might have other opinions on this and might rather travel alone
