Well, as Count Dracula once said, Bobert, "You can never have too many bats."

You should consider purchasing a large pipe organ and start playing it madly and majestically in the wee hours of the night to help inspire these "children of the night". With luck, you may even get some packs of wolves to hang out near your property and serenade you by moonlight. These animal "familiars" can then be used to keep away undesirables, like Republicans and NASCAR fans... ;-)
