The school is called Stadium High School. It is a real high school in Tacoma, WA. When I was a kid, I always thought it was weird when I watched this movie because everywhere they go for prom and their dates are in Seattle but their school is in Tacoma. About 33 miles (53 km) away from each other.
Also, I thought it would be fun to go paintballing like they did in the movie but while the park is real (Gas Works Park), sadly they don't have paintballing there.
