Wow, what would I do..? I can think of about a billion and one things..(some of which would be in the adult section..lol).
I'd motherlode it to death for sure. Hang out downtown and get to know a vampire. Then I'd hunt down the perfect guy..(one of my own creations, not the fugly townies). A wild romance, a marriage, a couple kids....then, when all seemed perfect, I'd invite my vamp friend over for a couple "bites". Live forever...muahahahaha.
(with the perfect guy, at least til somebody deleted my neighborhood)
