What are your favourite annual Second Life events? - eviltoast

For me Fantasy Faire is definitely the one I am looking forward to most. They just have the best mix of stunning regions and avatars, great stories and music on the radio, amazing events for the whole faire and they somehow even manage to integrate the Relay for Life donations and remembrance of those we lost into the event without spoiling the mood of either the sad or the happy parts of the event.

In the past I was also looking forward to Mario2 Helstein’s seasonal light shows but sadly he stopped doing those.

Since Linden Labs is notoriously bad about letting us know what is going on, what are your favourite events that others might not even know about?
