What an excellent anecdote! Thanks for sharing this. It is honestly the most inspiring thing I've read in at least a month. Sincerely, Thanks.
Shoot fast film so you have more time with the Mrs.
Take a polaroid ;)
Use her tactics: whatever you do, do make it appear you are doing it for her, or it's really she who wants you to do it ;)
And by the way, do exactly everything you would do after 10 years of marriage. Divorcing after having had children is not good behaviour. ;)
Be yourself. Don't be a French poodle ;)
She married a photographer. It's also your trip not just hers!
(Excess number of ;) due to the inevitable serious rebuking comments, although behind irony there can be a serious thought).
Thanks everyone. I ended up taking an F100 with a 24-120, Nikonos V with 35mm, Horizon 202, and an old Voigtlander folder (for our layover in SF). We also took along an Oly XA by accident, as it was in her handbag. Didn't have to worry about my photo taking leaving her with little to do - she shot over 1700 on our D70s.
