I'm looking for information on prom dances for couples that have
already graduated from highschool and college.  I would prefer dates
around the end of this year (04) to the beginning of next year (05). 
My primary interest would be dances that are in the chicagoland area,
but would also be interested in info for dances in California.  I
don't want to be a chaperon, but rather actually have a date and
attend the dance as a participant.  I am 24, and so is my date, so any
dances that have a 21 age limit is fine.  For the dances in California
I would like locations that are within a reasonable driving distance
to one of the major airports as I would have to fly in and drive to
the dance.  Thanks in advance for your
help.

are you looking for organized balls, or dances (not as dressy as a
prom, but not a club), or specific "proms"?

I'm looking for something as dressy as a prom.  Thanks.
