“Discover Marina del Rey Day 2007,” an annual day of family fun and activities, will take place from 11 a.m. to 4 p.m. Sunday, October 7th, in Burton Chace Park, 13650 Mindanao Way, Marina del Rey.

The event, presented by Arrowhead Mountain Spring Water and sponsored by Los Angeles County Supervisor Don Knabe and the County Department of Beaches and Harbors, is expected to draw over 3,000 people.

“Every year it gets bigger and bigger,” said Debbie Talbot, marketing analyst for the Department of Beaches and Harbors. “The community loves it. The kids love it every year.”

Events this year include some of the most popular offerings of past years, such as the air-sea rescue demonstration in the Marina’s main channel by the United States Coast Guard and the Los Angeles County Fire Department — and the inflatable games for children, according to organizers.

Though the event is presented free to the public, those who want to use the inflatable games pay $5 for a wristband, which will also allow access to snack carts and a pumpkin from the pumpkin patch.

Food and beverages are also available for sale in Burton Chace Park.

Among other events this year are a screening at noon, presented by the Los Angeles County Public Library and Sony Pictures, of the animated film Surf’s Up.

The Venice High School choral group The Allegros will perform from 12:30 to 1 p.m., followed from 1 to 3 p.m. by a concert in the park with the Susie Hansen Latin Band, presented by the Los Angeles County Arts Commission and the recording industries Music Performance Fund, through the assistance of Professional Musicians Union Local 47.

The Bob Baker Marionettes will present performances throughout the day, preceded by Children’s Storytime by the Lloyd Taber-Marina del Rey Library children’s librarian Kyla Kothman.

The Los Angeles County Department of Parks and Recreation will offer arts and crafts workshops and the Department of Beaches and Harbors W.A.T.E.R. Youth Program will offer leisure kayaking from noon to 3 p.m. in the main channel for visitors ages six and up.

Throughout the day, a variety of exhibitor booths will offer information on health, safety and the environment.

Additionally, a tour of the Marina del Rey Anglers/Ocean Resources Enhancement Program White Bass Grow Out Pen will allow visitors to watch the counting and releasing of sea bass. The group will also sponsor youth fishing off the fishing pier for visitors ages seven to 15.

Parking for the day is available at $5 in Los Angeles County Lot 4, near the park, at 13500 Mindanao Way.
