alternatively, if weaseling doesn't work, break into the sjf track and field storage room, grab one of those pole vault sticks and use it to hurl yourself over the fence and onto the field.* upon landing, spring for the sidelines and immerse yourself in the crowd to avoid detection from security.
*if there's a fence around the field.
note: this may not be necessary if you are able to see through the fence. in that case, you can stand there watching and disregard the pole-vault/avoiding security component of this plan.
either way, stop for a garbage plate on the way home.
