Heading out to the West Hollywood Halloween Carnaval tonight? You'll be joined by about 499,999 other people making the trek to WeHo, so plan to carpool, cab or hoof it, or take the city's free shuttle.

The city is offering a free "FrankenRide" shuttle that will stop at all Metro bus stops along Santa Monica Boulevard between Plummer Park and La Cienega Boulevard. There are also several public lots but they'll be charging $20 per car.

This year's theme is Noir Night, with a Noir City stage on Santa Monica Boulevard and San Vicente Boulevard emceed by Jeffrey Damnit. There's also a "Speakeasy Stage" and a "Pulp Friction Stage." For more info, see the WeHo site.
