CLEVELAND -- While the rules of the game remain the same, that's not the case off the football field.
The Browns home opener began with fans being asked to follow stricter security measures.
The Cleveland Municipal Lot was packed on Sunday.
For die-hard Browns fans, like Keri Loughry, the pregame tailgating is an event.
"This is Browns town and you can't stop a party," she told Fox 8 News.
Mandi Acierno and 25 of her closest Browns fans tailgate before every Browns home game.
"We come. We drink. We have fun and we support the Browns," Acierno added.
But this year, new signs remind fans that open containers, consuming alcohol and public intoxication in the Municipal Lot are prohibited.
Browns Fan Nick Vento said the rule should not be too hard to follow.
"All people need to do is exercise common sense. Very simple. Have a good time. Be smart," he said.
There are also new security measures in place at Cleveland Browns Stadium.
While the evasive pat-downs are gone, each fan undergoes a full-body search by a metal-detecting wand.
Security personnel are particularly looking for any concealed weapons.
Every bag is also checked.
Eagles Fan Robbie Reid found he could not bring an umbrella into the stadium on Sunday.
“We checked the admissions policy into the game, nothing about umbrellas -- just no outside beer, no signs with sticks or metal poles, things like that," Reid said.
But Browns fans like Sharon Rader told Fox 8 News that they are fine with the new security measures.
"Because of 9-11 and everything. I think it is a real good practice. So, very good," she said.
The city will find no need to throw a penalty flag, if Browns fans play by the new rules.
