                However, it's really not sufficient.


                I could create object A today, object B tomorrow, and
drop object A the day after tomorrow.  Then, Brandon's query will return
yesterday's date, rather than the day before yesterday.


                There's no good, obvious way around this, that I can
see.  I'm just pointing out a possible weakness in the strategy.
