The Odessa Bronchos and Permian Panthers are preparing for their yearly rivalry game on the football field.
Dozens of fans made sure they got a ticket to the big game by getting up in the middle of the night and heading to Ratliff Stadium - some even camped out overnight.
Before the sunrise, there were 67 cars lined up to get into the stadium.
Fans say it's all about tradition and the cross-town rivalry.
MOJO fan Lisa Lewis waited for more than 12 hours - staying in her car overnight.
"Looks like I'm lucky number one," she said.
Lewis was first in line for last year's ticket sales as well.
All of her children graduated from Permian.
"I love my family," she said. "Let me tell you kids, this is for you I wouldn't do this for anybody else."
Todd Vesely, Executive Director of Athletics for ECISD, is pleased with the friendly rivalry.
"The rivalry between the east side and the west side runs deep for as long as the second high school was opened," Vesely said. "Those rivalries run through the generations."
While today's ticket sales went smoothly, the ECISD Police department hopes the traffic at the game does too.
With 20,000 fans parking, and filing in and out of the stadium, Police Chief Mark Rowden wants to make sure you have a plan.
"It's important that everybody understand that it's going to take a while to get into the stadium and it's going to take a while to get out of the stadium," Rowden said. "We just ask for people's patience and understanding because when you get that number of people in one place it's just going to take some time."
