Organizers of the 45th annual Ole Brook Festival are hoping for great weather and good vibes for a fantastic show.

The two-day festival begins today with several of the food vendors opening for lunch and staying open for the Ole Brook Fest Street Dance at the main stage on Railroad Avenue and Chickasaw Street. The free concert is 6 to 9 p.m. and features Four Way Stop and The Bridge Band.

The Ole Brook Festival began in 1974 so the public is encouraged to dress to reflect the show’s beginnings.

“Show us your grooviest gear and jam to the best of the ’70s and some new stuff, too,” said Katie Nations with the Brookhaven-Lincoln County Chamber of Commerce, which organizes the events.

Trophies for best outfit will be awarded.

The festival is off with a bang Saturday when the 10th annual Pink Sisters 5K Foam Run/Walk begins at 8 a.m. in front of the main stage. The run will not be timed.

The cost of the run is $25 per adult participant and $12 per child age 10 and under.  Proceeds from the 5K will stay in Lincoln County to help breast cancer patients who live locally.

Members of the Pink Sisters are all breast cancer survivors, but anyone can participate in the 5K and anyone can get involved — survivors, patients, families of patients and survivors, or anyone who loves someone affected by breast cancer.

The Ole Brook Antique Car Show starts at 9 a.m. on Railroad Avenue. Registration begins at 8 a.m. and costs $10 per vehicle.

The Kidzone, which includes 12 attractions, opens at 9 a.m. in the north parking lot. Armbands for unlimited access are $10.

The food trucks will fill the south parking lot and are open all day, she said.

Live entertainment will be featured on the main stage and includes rock, blues, jazz and gospel as well as a singer-songwriter showcase.

Parking and admission into the festival, car show and street dance are free.

The Chamber is hosting a Git Up Challenge at noon on the main stage for children 12 and younger. Entry is free with an armband and donations will be collected for Pink Sisters. The winner will receive a plaque and a cash prize.

More than 130 arts and crafts vendors will line Whitworth Avenue from Monticello Street to Chickasaw Street. Vendors will not be set up on Cherokee Street this year, Nations said.

Expect traffic delays today downtown as the main stage is set up at Cherokee Street and Railroad Avenue. Railroad will reopen immediately following the stage set-up, then close again at 5 p.m. Through traffic from First Street to Cherokee Street will be blocked until the festival ends Saturday at 4 p.m.

Several streets will be closed today at 5 p.m. for vendors to begin setup: South Whitworth from Monticello Street to Chickasaw Street and Railroad Avenue from Monticello Street to Chickasaw Street. Streets will reopen at 4 p.m. Saturday after vendors pack up and leave the area.

Arrow Disposal Service will provide garbage pickup during the festival.
