One category you may wish to add are those non-mystery, non-HH boxes
with non-specific or indeterminate locations. I can think of a handful
in this category off the top of my head. I'm not sure how (or if)
the lbna webmasters categorized these, and I am certain that putting
such a category in a database prolly would be useless (and prolly most
people who create these things wouldn't use a database anyway), but
as a nerd who enjoys problem analysis, I think the best way to promote
thinking outside the box is to create boxes :-)

Oh, and congrats to whomever found the jackpot ... use it wisely ...

Cheers
