FORT MYERS, Fla.- We're one day away from the largest nighttime parade in the Southeast. There will be about 200 groups marching from Fort Myers High School to downtown Fort Myers. It's all for the Edison Festival of Light Grand Parade. Preparations are under way right now.

Organizers say things are shaping up pretty well. The sound stage is set up near Centennial Park for the pre-parade celebration. Also, many vendors have set up for the festival's Crafts on the River going on all weekend. But the preps happen weeks in advance, when families mark off the sidewalk, reserving their spot for watching the parade go by.

Organizers say everything is running smoothly, with the biggest issue being potential rain. The floats should be all covered up in the meantime, and ready to stage at Fort Myers High School tomorrow morning.

Parts of Cleveland Avenue, as well as parts of MLK and a large portion of downtown will be shut down, most of them after 5:00 p.m. Click here for a complete list of road closures.

This year is expected to be the biggest ever. Organizers say they expect to pack around 300,000 people along the parade route. That number includes participants and attendees.

The parade starts at 7:00 p.m.
