My first try took me to a casino in Janus (Janus 127, 127, 66). And I spent a bit of time flying around after that and registered several sims that were new to the database. Woot! Eventually, I ended up in a parcel named Le Cimetiere that listed "vampire sex, goth and punk night club" as areas of interest. What I thought was interesting was that the area was surrounded by a very tall wall textured like the night sky.
While this looks a little odd when you are flying (and stops your progress when you fly into it), when you are on the ground it does provide the illusion of darkness.
Which is certainly a plus if you are a vampire. There is also a churchyard for those of you who are participating in the Dearly Departed photo competition.

PS Ordinal Malaprop's Slurlchatter (available in the "Items Which are Free" box at Ordinal Enterprises has also proven to be an invaluable! Much like her Slurlbuilder, the Slurlchatter is an in-world tool that creates an on-the-spot slurl when clicked. An excellent resource for Baedeker entries. I have chosen to wear it on my right arm when exploring. It saves a great deal of time by eleminating the viscious cycle of rezzing and deleting.
