HIDALGO — Santa Claus, the Cat in the Hat and Coca Cola’s iconic polar bear joined city leaders in announcing the theme of this year’s 28th annual Festival of Lights Thursday afternoon.

The whimsical world of Dr. Seuss, which includes classics such as The Grinch, The Cat in the Hat and Thing One and Thing Two, will be featured at this year’s event.

The month-long event offers residents from across the Rio Grande Valley, northern Mexico and even Canada, an opportunity to tour more than 500 Christmas light displays located throughout the city’s main corridor. City leaders estimate more than 5 million lights will illuminate the sky on any given night.

All of the displays are created and setup by staff at the city’s parks and streets department, which work for months on the tedious displays.

The event kicks off Nov. 30 with an illuminated parade and runs through the end of December. About 800,000 tours are given each year, city officials said at a press conference Thursday. Tours start at $5. There are also tours with dinner packages available for $12.

Coca Cola was once again introduced as the event’s title sponsor, marking the second year the worldwide company partners with the city of Hidalgo.

“Those of you who have not attended, shame on you,” Coca Cola representative Frank Sanchez joked.

Every Tuesday, the Coca Cola polar bear will be available for pictures from 8 to 10 p.m., and visitors can also take advantage of Santa’s workshop and a carnival.
