Another odd-ball question, but how to you handle a plural noun's (like "crew", where the entire crew is referred to as a singular entity) possessive? Do you write "a crew's lives", "a crew's life" or "a crews's lives".
My first impulse is to use the singular for crew, while using the plural for "lives", but I can't argue for why that's the proper usage.
Ross, do you have any lengthy, technical grammar rules for us to chew on? I tried looking it up, but couldn't find anything specific, just vague generalities.
