Forget drive-through chapels—the hottest new trend is curbside weddings. For just $99, the Las Vegas Wedding Wagon will marry you in 15 minutes, max, at your desired location (the “Welcome to Las Vegas” sign is a crowd-pleaser). Co-founders Andy Gonzalez and James Cass ditched their corporate jobs to find their true calling. Inspired by the Hangover Truck, which gives tuckered-out revelers intravenous aid, their mobile matrimony idea was borne.

Sure, it sounds like a scene in a rom-com: Lonely girl meets lonely boy at wild party, and after a brief, but promising conversation (and five too many rounds of margaritas) they decide to make it forever. But there’s only one problem: They don't have a car, so they text the Wedding Truck to meet them on the Strip. Not so fast—they require that you obtain an official marriage license in advance, but you can speed up the process with this online form. Gonzalez and Cass are available for immediate service between 12 – 9 pm, but you can schedule your nuptials in advance on their website.

I recently met with Kate Harrison, creator of greenbrideguide.com and author of "The Green Bride Guide,” the definitive bible on how to have an eco-chic wedding on any budget.
