Hey, we go two pretty good size arroyos, why can't we "light" them up?

HARLINGEN — Santa hats filled McKelvey Park Thursday as community members gathered to usher in the Christmas season on a cool fall night.
The 24th annual Arroyo Holiday Lighting Ceremony began festivities at 6:30 p.m. with singing and dancing, which lasted into the night.
Dr. Nolan Perez was chosen as this year’s honorary grand marshal, a title that Parks and Recreation Program Coordinator Esmeralda Martinez said is given to a member of the community who has given back to the community year round.
Perez thanked the community and said that it was a huge honor to participate in the lighting ceremony. He added that Christmas was a special time for families to come together.
Perez, along with those in attendance, counted down from 10, before he lit the Christmas lights at the park.
“The lights came on and I felt like Christmas was already here,” 11-year-old Nancy Garza from Harlingen said.
In addition to the lighting, local schools helped spread Christmas cheer, including the Harlingen High School South Southern Stars Drill Team, Lamar Elementary School Cheer, Dance and Twirl Team and Saint Anthony’s School Choir.
Mayor Chris Boswell said the arroyo lighting was a fine Harlingen tradition and a perfect opportunity for members of the community to come out and celebrate the talent being showcased.
