We may have two major photographers and several minor ones, doesn't seem to matter. We always forget about it until we're headed out the door to our far away homes. Crazy. So this time, we remembered. Not at Eldest/Admin's wedding. Not at Eldest Son's either, but this time we got it.
I do believe our new standard shall be:
'If there is more than one Birthday Crown in the group, a Family Photo shall henceforth be mandatory, so saith the Grand PooBah.'
