Just stumbled accross this looking for something else. This couple was looking for a Las Vegas hookup. Obviously too late, but thought maybe they might still be open. Maybe they are even a member here?

Good luck!
I imagine you would want to be as careful with craigslist as with any other medium where you might meet anonymous opponents. Talk first on the net and voice verify preferably on the net so they don't have your phone number, meet in a public place first, never go alone. Just common sense stuff. But you are right to be careful, for sure. Lots of crazies out here in cyberspace.
