Where am I describing?

In the car park there are lots of people. It’s full of customers of all ages. When you enter the building there are jumbo sized lines of people who are waiting.  When you come in the stage area, you will hear booming noises. As it starts, the crowd cheers and whistles. Suddenly, the wave dance begins and everyone cheer more louder. The public screams and shouts. you can see flags and people a circular structure. you see people waving there are fake grass. the coach on the field whistles and holds the yellow card buzzzzzzz the bell rings the bored shows. Cheerful, cool and loud.
