With the athletes, are thousands more friends, family and other spectators cheering them on.
"Just a great atmosphere here and here to cheer on the bison," said Becky Mai from McCook.
While the weather was hot on Friday, storms are expected to move in on Saturday.
"We're watching it, minute by minute we got an eye on things, our contingency plan is to keep all events here on site, manage the weather, and in severe weather we may move events over to Boys Town if we had to," said Assistant Director of the NSAA Nate Neuhaus.
In case extreme severe weather arrives, Neuhaus said the athletes will go to Burke High and the other spectators will seek shelter on their own.
But the potential of that severe weather doesn't scare some of these fans away, "We'll bring an umbrella and we'll be here I mean a little rain doesn't hurt anybody so we'll be here regardless," said Lena Gines.
The events continue until 8p.m. on Friday and 6p.m. on Saturday.
