Well, this is your chance to experience the red yuletide in comfort of your own home, sitting at your computer. M2santa will be leading the2nd annual Virtual Santarchy rampage on Dec 23rd:
Drinking, dancing, a snowball fight, crashing the shopping mall and a visit to the red light district.
Looks like festive debauchery will be had by all. Find that drunken reindeer or naughty elf avatar and head over to Benvolio (click here to teleport) starting at 5PM PST tomorrow.
(For those looking for more traditional, respectful holiday gatherings, you might prefer the official "Winterfaire" gatherings in SL.)
