That post was entirely incorrect - both the date and location are different.
After digging around, here are the details I now feel safe reporting.
According to the Dark Lord Day 2008 event page on BeerAdvocate.com:
DarkLord Day 2008 Saturday April 26th 11Am-10:30pmFurthermore, Floydicus himself reports these details in the BeerAdvocate forums:
DarkLord Day 2008 is the only day of the year to buy Three Floyds DarkLord Russian Imperial stout.DLD is a festival where participants can meet other beer enthusiasts, sample beers from all over ,buy DarkLord, try Oak Aged Dark Lord Russian Imperial Stout ,eat BBQ, Listen to live music.
Darklord Day 2008 will be greatly improved to accommodate larger crowds, including expanded parking, more porta johns, shorter lines and more food choices.
