LORELAI: What are you doing here?
EMILY: Well, I was thinking about possibly having our next DAR luncheon here.
It was established in the previous season that the Hartford DAR hold their monthly meetings at the Independence Inn, which Lorelai had to agree to in order to get help with a loan she needed, in “Secrets and Loans”.
The monthly meeting included a luncheon, but this DAR luncheon is presumably something separate from, and far more elaborate than, the monthly meeting luncheons. Lorelai books the DAR luncheon for the 15th March, which was a Saturday in 2003. (There may be some joke here about the Ides of March – the 15th of March – the day on which Julius Caesar was assassinated).
