It is very loud and hot, but fun to attend.
I recommend it for race fans. The nitro cars are extremely loud. When they shoot off the starting line, they cause the seats to vibrate. Sometimes the top of the car blows off which is scary, but interesting to see in the pits afterwards.
In between the different events, you can walk around in the pits. Meet the different drivers, watch the crew work on the cars, and get autographs.
If you have sensative ears or young children, I do not recommend attending.
