smoking weed at a concert? dallas

I'm about to go to a ffdp concert in Dallas at the palladium ballroom this weekend.
EVERY concert I've been to was outside or had to many people to worry about the stoner section.
What I was wondering is will a relatively small concert ballroom check me at the door or will I get in trouble if I light if a blunt or two.
Its in Dallas.

 

Well yeah I just mean will security trip or should I just wait till someone else lights up
